B Correct answer
Explanation

Caryopsis is a one-seeded fruit where the pericarp (fruit wall) is completely fused with the seed coat, making them indistinguishable. This is characteristic of cereals like wheat and maize. Achene has a separate pericarp, cypsela is similar but found in Asteraceae, and nut is a hard one-seeded fruit with unfused walls.
