?

Detailed Explanation

The correct answer is A) Sporopollenin.

The term pollen viability describes the pollen's capacity to carry out its characteristic of turning in male gametes to the embryo sac.

Pollen grain stability is highly varied and to some extent, dependent on the surrounding temperature and humidity.

Sporopollenin is one of the maximum chemically inert organic polymers. It is chemically very strong and is commonly properly present.

Due to sporopollenin, pollen grains from some Rosaceae, Leguminosae and Solanaceae plants remain viable for a month.
