That depends on your exact position! Standing normally, it might be in the area of the navel; if you lift your arms or your legs, the center of gravity will be higher, if you bend over, the center of gravity might actually be outside your body (somewhere in front of your navel or so), etc.
When seated in a relaxed position say in a couch or behind a wheel in a car, the center of mass of a body is between the heart and the navel, very close to where the diaphragm is (closer to the heart than the navel). Here we assume that the knees are bent to a degree and the body is slightly tilted backwards, the spine is curved inward and the legs are slightly lifted. When the arms change position, that is stretched forward to the steering wheel, the CMB moves forward, when reclining in a couch the CMB moves backward. This is again for a person of average weight and height and body mass index. Different body shapes will move the CMB towards the bulk in the body. Weightlifters will have more mass in their torso and arms and hence the CMB will be higher than in females with larger hips and fat legs where the CMB will move toward the ovaries.
The point is inside your torso, roughly halfway between the skin of your tummy and the skin of your back, and centered left-to-right.
It's somewhat lower in females, because of the relatively larger mass in the hips, and somewhat higher in males, because of the relatively larger mass in the chest and shoulders.
A close approximation of a person's CG while sitting is their belly-button.
Behind the belly button, in the center of the abdomen.
Often slightly lower in women, slightly higher in men.
it is exactly on/in the belly button.

The center of gravity is the theoretical point where all the body weight is concentrated or the theoretical point about which the body weight is evenly distributed. If a body is of uniform density and has a symmetrical shape the center of gravity is in the geometric center. If the object is not symmetrical and does not have uniform density, it is more difficult to describe the location of its center of gravity.
The center of gravity of a solid body does not always lie within the body. An example of this is a hula hoop. The center of gravity does not lie on the hoop that rotates.
The human body is bilatertally symmetrical because the left and right halves of the body mirror each other, as you can see in the image to the left.as such the centre of mass of the human body should lie in its geometrical centre of the bodyIn most people the center of mass is around the belt buckle andabout 4" in. A Japanese martial arts instructor could be used to show you where the "hara" is. This approximately the same location.
That "point" in a body where the entire weight of the body can be represented to be present. Extend your knowledge by exploring where the center of gravity would be for metal shapes formed in the shapes of circular, square, rectanglar, hexagonal rings with metal rods. Where would the center of gravity be, on the ring or outside the ring?

If you want to define total centre of gravity of a person, you must know:the mass of each body segmentsthe x, y and z coordinate of centre of gravity of each body segment (3D motion)

If the gravity is not constant over the body.
if you stand with your feet evenly apart, directly between both your legs is your center of gravity.
No. For example, a ring has a center of gravity in the center of the ring, not on any part of the ring.
yes ,when centre of gravity and center of mass is at a st.line the body is balanced.

Center of gravity is supposed to act at the centroid of the body. while center of buoyancy is the center of gravity of fluid displaced . so they cant be at single point. if the body is completely submerged and homogenous then both cg and cb will coincide
