Which fruit is not a stone fruit?

• A. Cherries
• B. Nectarines
• C. Plum
• D. Apples

Answer: (D)

Stone fruits are drupes that contain a single hard pit inside the fleshy fruit. That pit protects one seed and is formed by the hard endocarp. Cherries, nectarines, and plums all have one seed encased in that hard stone, so they are stone fruits. Apples are not stone fruits. They are pomes, with the edible flesh surrounding a central core that holds multiple seeds. The seed-containing structure is different from the single hard pit of a stone fruit. So, the fruit that is not a stone fruit is apples.
