Concept: This question tests your understanding of fruit development, specifically focusing on the characteristics of a drupe and the type of ovary it develops from, using mango and coconut as examples.

Why (A) is correct: Both mango and coconut are classic examples of drupe fruits. A drupe is characterized by having a fleshy outer part (exocarp and mesocarp) and a hard, stony inner part (endocarp) that encloses the seed. They develop from a monocarpellary superior ovary, meaning the ovary is made up of a single carpel and is positioned above the other floral parts. Drupes are typically one-seeded, with the hard endocarp protecting this single seed.

Why other options are wrong:

• (B) Monocarpellary superior ovaries and are many seeded: Drupes are typically one-seeded, not many-seeded.
• (C) Polycarpellary superior ovaries and is one seeded: Mango and coconut develop from a monocarpellary (single carpel) ovary, not polycarpellary (multiple carpels).
• (D) Polycarpellary superior ovaries and are many seeded: This is incorrect on both counts; drupes are monocarpellary and one-seeded.

NEET Tip: Remember that drupes are also called 'stone fruits' due to their hard endocarp. Examples like mango, coconut, peach, plum, and cherry are important to recall.

Correct Answer: (A)
