To determine the correct answer, we need to understand the structure of fruits in botanical terms. The question asks about a fruit with a thin epicarp, fleshy mesocarp, and stone-like hard endocarp.
Here is a breakdown of the relevant fruit structure:
- Epicarp: The outermost layer of the fruit, often referred to as the skin.
- Mesocarp: The middle layer of the fruit, which is typically fleshy and juicy.
- Endocarp: The innermost layer that surrounds the seed. In some fruits, this becomes very hard and stonelike.
Now, let's examine the given options:
- Melon: Generally has a thin epicarp, fleshy mesocarp, but a soft endocarp.
- Apricot: Has a thin epicarp, fleshy mesocarp, and a hard stone-like endocarp, also known as a drupe.
- Lemon: Has a thin epicarp, a fleshy mesocarp, but its seeds are not enclosed in a hard endocarp.
- Kiwi: Unlike a drupe, kiwis have a fleshy pericarp and a soft endocarp.
Option 2, Apricot, fits the description given in the question—having a thin epicarp, a fleshy mesocarp, and a hard endocarp, which is characteristic of drupes.
Therefore, the correct answer is Apricot.
