The correct option is A Multicarpellary apocarpous ovary
The fruit which develops from multicarpellary apocarpous ovary is called as an aggregate fruit. An aggregate fruit is a fruit that develops from the merger of several ovaries that were separate in a single flower. In contrast, a simple fruit develops from one ovary.
Not all flowers with multiple ovaries form aggregate fruit; the ovaries of some flowers do not become tightly joined together to make a larger fruit. Aggregate fruits may also be accessory fruits, in which parts of the flower other than the ovary become fleshy and form part of the fruit.
Thus, the correct answer is option A.
