All of the following reproductive structures are considered female except a. stigma. b. petal. c. ovary. d. ovule.

The correct answer is option - B. petal.

Explanation:

The female reproductive organs of a flower are included carpel and each carpel has an ovary, style, and stigma. The ovary is the organ that produces ovules (the female reproductive cells). Style is a tube-like structure present on the ovary. Stigma is the structure that receives the pollen during fertilization.

petal is the leaves that are modified and covers the reproductive structure of the plant. Generally, petals are bright in color to attract pollinators.

Thus, the correct answer is option B, petal.
