Concept: This question tests knowledge about the edible parts of fruits, specifically focusing on the structure of a banana fruit.

Why (C) is correct: The edible part of a banana is primarily the fleshy inner part, which develops from the endocarp and a less developed mesocarp. The banana fruit is a berry, and its pericarp (fruit wall) is differentiated into an outer epicarp (skin), a middle mesocarp, and an inner endocarp. In bananas, the endocarp becomes soft and fleshy, while the mesocarp also contributes to the edible pulp but to a lesser extent.

Why other options are wrong:

• (A) epicarp: The epicarp is the outer skin, which is peeled off and not eaten.
• (B) mesocarp and less developed endocarp: This is incorrect; the endocarp is the more developed and primary edible part.
• (D) epicarp and mesocarp: The epicarp is not edible.

Common Mistake: Students often confuse the relative contributions of the mesocarp and endocarp to the edible portion of different fruits. For bananas, remember the endocarp is key.

NEET Tip: For fruit morphology, visualize the fruit and its layers. For example, in mango, the mesocarp is edible; in coconut, the endocarp is hard and stony, and the endosperm is edible. Knowing the fruit type (berry, drupe, etc.) often helps in identifying edible parts.

Correct Answer: (C)
