The correct answer is option 2 - aggregate.

An aggregate fruit is formed from several separate carpels of one flower, which are fused together to form a single fruit. In a multicarpellary, apocarpous gynoecium, each carpel is separate and forms an individual fruit. Therefore, when these separate fruits develop from the multiple carpels of the flower, they fuse together to form an aggregate fruit. Examples of aggregate fruits include strawberries, raspberries, and blackberries.

Option 1 - composite, is incorrect because a composite fruit is a type of fruit that is composed of multiple individual flowers (florets) arranged together on a common receptacle, as seen in pineapples.

Option 3 - simple, is incorrect because a simple fruit is formed from a single ovary.

Option 4 - multiple, is incorrect because a multiple fruit is formed from the fusion of multiple individual flowers from an inflorescence, such as in pineapples or mulberries.
