The correct option is C Sporopollenin occurs in the area of germ pores only
Sporopollenin is a major component of the tough outer walls called as exines. It is the most resistant organic material present on the Earth. It protect the pollen grains from external environment and help them in surviving during harsh conditions like high temperature, heavy rainfall, etc. Germ pores are the openings present in the exine layer where sporopollenin is absent.
