WebCorrect option is A) DNA and RNA are made up of nucleotides. They are of 2 types, purines and pyrimidines. Purines are 2 carbon - nitrogen-containing rings and pyrimidines are 3 carbon - nitrogen-containing cycle. Purines are adenine and guanine and pyrimidines are cytosine and thymines. So, option A " Cytosine and Thymine" is the correct answer.
