Which option lists the four floral whorls correctly?

• A. Sepal-Calyx; Petal-Corolla; Stamen-Androecium; Ovary-Gynoecium
• B. Calyx-Sepal; Corolla-Petal; Androecium-Stamen; Gynoecium-Ovary
• C. Sepal-Petal; Calyx-Calyx; Stamen-Ovary; Gynoecium-Gynoecium
• D. Petal-Calyx; Sepal-Calyx; Stamen-Gynoecium; Ovary-Ovary

Answer: (A)

Floral arrangement is built from four concentric whorls, each named for the organs they form: calyx, corolla, androecium, and gynoecium. The calyx is made up of sepals; the corolla is made up of petals; the androecium consists of stamens; the gynoecium is the female whorl that contains the ovary (and other carpels). The option that pairs Sepal with the calyx, Petal with the corolla, Stamen with the androecium, and Ovary with the gynoecium shows these direct relationships clearly: each organ corresponds to its respective whorl, and it acknowledges that the ovary is part of the gynoecium. The other choices mix up these relationships or oversimplify the gynoecium, making them less precise.
