Question

Jackfruit is multiple fruit formed from
A. Single ripened ovary
B. Inflorescence
C. Flower with many free carpels
D. Flower with many partially fused carpels

Answer 1

Its exceptionally large size is one special feature of the jackfruit. It is the world's largest tree fruit and can reach a mass of up to 80 pounds (35 kg).
Jackfruit has a sweet and fruity taste that is subtle. Similar to a combination of fruits, including apples, pineapples, mangoes and bananas, it was said to taste similar.

Complete answer:
Multiple fruits are fruiting bodies, also called collective fruits, produced from a cluster of fruiting flowers, the inflorescence. A fruit is formed by every flower in the inflorescence, but these mature into a single mass in which each flower has produced a true fruit. The mass is called an infructescence after flowering. Fig, pineapple, mulberry, Osage-orange, and breadfruit are examples.
First, it produces an inflorescence of white flowers called a head. Each flower grows into a drupe after fertilisation, and as the drupes grow, they become connate (fusion) into a multiple fleshy fruit called a syncarp. Many dried fruits are also available.

Plane tree, several multi-flower achenes, in a single fruit structure
Mulberry. Multiple flowers form a single fruit
Jackfruit Multiple flowers form one fruit,
Fig. Inside the inverted inflorescence, multiple flowers similar to mulberry infructescence form a multiple fruit. It's called a Syconium in this shape.
From the complete inflorescence, which in the case of jack fruits is spadix, multiple fruits grow and it is therefore called a form of fruit sorosis.
Flowers with several free carpels, as seen in aggregate fruits, are apocarpous.
A single ripened ovary leads to a simple fruit being formed.
Syncarpous is the name of Fused Carpels.

Hence, the correct answer is option (B)

Note: For the sweetly acid yet insipid pulp around the seeds, the greenish unripe fruit is cooked as a vegetable, and the brown ripened fruit is eaten fresh. The seeds are locally cooked and eaten.
