Answer 1

Hint: In the ber fruit outer part is the edible part and contains two layers, while the inner part is lignified. This type of fruit is also called stone fruit. Mango is an example of this type of fruit. These develop from superior ovaries.

Complete answer:
The fruit of Ber (Ziziphus mauritiana), is a drupe fruit which means that the outer part of fleshy which contains the epicarp and mesocarp, while the endocarp is hard and stony and it contains the seed.

Additional Information: Drupe is a simple fleshy fruit which usually contains a single seed like in cheery and olive. Drupe fruits arise
from a single ovary of an individual flower.
The outer ovary wall is thin while the middle layer is thick and fleshy (tough in almond and fibrous in coconut) and the innermost layer is hard and stony and is also called a pit. The innermost layer is often confused with the seed.
Berry is the soft, rounded, pulpy, and fleshy fruits that are developed from the ovary of the single flower while the nut is the hard fruit having an outer hard shell which is the inedible part and the inner part is the edible part.

So, the correct answer is, ‘ Drupe.’

Note: In some aggregate fruits like blackberry which are not true berries in the many small drupes are clumped together. These types of fruits are the result of numerous fused carpels from a single flower.
A nut is a dry dehiscent fruit in which pericarp is hard and stony, inside that, the seed is present which is edible.
