Aggregate fruits or etecrio are those fruits that develops from the merger of multicarpellary apocarpus gynoecium (ovary). In contrast, a simple fruit develops from one ovary. Aggregate fruit may also be called accessory fruits in which part of the flower other than the ovary become fleshy and form part of the fruit, e.g., raspberry, blackberries, and strawberries are examples of aggregate fruit.

Explanation:
An aggregate fruit is a fruit that develops from multiple ovaries in a single flower. Each ovary forms a separate fruit known as a "fruitlet", and all the fruitlets are arranged together to form a single structure. The aggregate fruit is a characteristic feature of certain plant families, such as the Rosaceae family.
Option A: Multicarpellary syncarpous gynoecium
In this type of gynoecium, the carpels are fused together to form a single pistil or ovary. The aggregate fruit does not develop from a syncarpous gynoecium because the carpels are not separate to form individual fruitlets.
Option B: Multicarpellary apocarpous gynoecium
In this type of gynoecium, the carpels are free or separate from each other. Each carpel has its own ovary. This type of gynoecium is characteristic of plants that produce aggregate fruits. Each ovary develops into a fruitlet, and all the fruitlets are joined together to form the aggregate fruit.
Option C: Complete inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem. While some fruits can develop from complete inflorescences, an aggregate fruit specifically develops from multiple ovaries in a single flower, not from the entire inflorescence.
Option D: Multicarpellary superior ovary
In this type of ovary position, the ovary is located above the attachment of other floral parts (sepals, petals, and stamens). The position of the ovary does not determine whether the fruit will be an aggregate fruit or not.
Therefore, the correct answer is option B, multicarpellary apocarpous gynoecium, as an aggregate fruit develops from multiple separate ovaries in a single flower.
