The correct options are
A Aggregate fruit - multiple ovaries, single flower
C Multiple fruit - multiple ovaries, many flowers
Both aggregate fruits and multiple fruits arise from multiple ovaries. But the major difference between them is the number of flowers involved. An aggregate fruit arises from a single flower containing multiple ovaries. A number of fruitlets as there are a number of free ovaries, each giving rise to one fruitlet. Sometimes, these fruitlets coalesce together appearing to be a single fruit but in many other cases, the fruitlets remain free from one another forming etaerio of fruitlets. Multiple fruit arises from ovaries of multiple flowers that fuse together to form a single fruit.
