The answer is a strawberry,I believe. Why? Well, a couple reasons No skin, smaller size, Seeds on the outside unlike any of the others. Also, the strawberry is the least similar in that it is a herbaceous vine, rather than a woody tree or shrub like the other ones, and it can reproduce asexually. It also is not just one Fruit like the others, it is actually formed up of Lots of tiny fruits forming one big fruit which we call a Strawberry. So, I believe that the answer peach is wrong. But, if anybody has any other suggestions that might enlighten me or others please feel free to elaborate on why you think a Peach is least like the others.
This is a tough question considering the apple and the pear are the only two of the group that bear a biological similarity in that each is a pome fruit encasing a number of seeds. The peach, on the other hand, is a single seeded drupe, and the strawberry consists of a large number of 1-seeded achenes bound together into a single fruit. This regards the fruit of these plants only.
However, if we consider the plants themselves, the strawberry is the least similar in that it is a herbaceous creeping vine, rather than a woody tree or shrub like the others, and can reproduce asexually through runners, and also because its "fruit" is actually a conglomerate of many tiny fruits forming a single fruit.
As the Strawberry is not technically a fruit the Strawberry is the answer.
