Step 1: Understand fruit classification.
A drupe (stone fruit) is a fleshy fruit with a thin skin, a soft mesocarp, and a hard endocarp (stone) enclosing the seed. Examples: mango, peach, coconut.
Step 2: Analyze other options.
(B) Pome – fleshy fruit derived from accessory tissue (apple, pear).
(C) Berry – fruit with many seeds embedded in fleshy pulp (tomato, grape).
(D) Sorosis – fruit formed by multiple flowers (pineapple, mulberry).
Step 3: Conclusion.
Thus, mango is classified as a drupe.
