The correct option is C Endocarp and less developed mesocarp
Edible part of Banana endocarp and less developed mesocarp. The fruit has been described as a leathery berry. There is a protective outer layer with numerous long, thin strings, which run lengthwise between the skin and the edible inner portion. The inner part of the common yellow dessert variety can be split lengthwise into three sections that correspond to the inner portions of the three carpels by manually deforming the unopened fruit. In cultivated varieties, the seeds are diminished nearly to non-existence, their remnants are tiny black specks in the interior of the fruit.
Therefore, the correct answer is option C.
