Verified by Experts

The correct Answer is:
C
Pollen exine is resistant to enzyme acition. The pollen wall is consisted of two layers, the outer exine and inner intine. The exine is chiefly made up of sporopollenin, which is derived by the oxidative polymerisation of carotenoids. Sporopollenin is one of the most resistant biological materials known. Exine is thin in beginning but become very thick with maturity.
