Best answer

Answer: 4. Sporopollenin

Sporopollenin, the material of the pollen exine, is extremely resistant to heat, acids, alkalis and enzymes.

So the exine stays intact for millions of years, helping fossil pollen studies. Pollenkitt and oil help in insect pollination, and the intine is cellulose and pectin that decays.
