Which fruit type has a single seed enclosed in a hard layer with soft, juicy flesh?

• A. Drupe
• B. Berry
• C. Citrus
• D. Pome

Answer: (A)

The idea here is recognizing a fruit that has one seed protected by a hard covering inside soft, juicy flesh. In a drupe, there is a single seed inside a hard endocarp (the stone) with the fleshy part around it being juicy and edible. That combination—one seed and a hard stone—fits fruits like peaches, plums, and cherries.

A berry, for contrast, has multiple seeds embedded throughout a fleshy pericarp. Citrus is a type of berry with a thick rind and many juice sacs. A pome has a core with several seeds, surrounded by edible flesh but without a hard stone enclosing a single seed. So the described fruit type is a drupe.
