Identify the type of flowers based on the position of calyx, corolla and androecium with respect to the ovary from the given figures (a) and (b)

A (a) Perigynous; (b) Epigynous
B (a) Perigynous; (b) Perigynous
C (a) Epigynous; (b) Hypogynous
D (a) Hypogynous; (b) Epigynous

The answer is B.

Solution

In both figures, the thalamus forms a cup-shaped structure around the ovary and the sepals, petals and stamens arise from its rim, at about the level of the ovary (ovary half-inferior). So both (a) and (b) are perigynous flowers.
