• A. hypogynous
• B. perigynous
• C. epigynous
• D. both (b) and (c)

Answer 1

Answer: (C)

epigynous

A perigynous flower has concave or cup-shaped thalamus forming rims or flanges, on which stamens, petals and sepals other whorls are placed around it. The ovary is said to be inferior.

Examples—pea, roses.

An epigynous flower is that in which the thalamus is hollow and cup-shaped, and completely fuses with the lower part of the pistil (ovary). The stamens, petals, and sepals are placed above the pistil. The ovary in epigynous flower is inferior. Examples— Sunflower, Cucurbita (B. Gourd), tuberose. So, the correct answer is C.
