In an analysis of the nucleotide composition of a double stranded DNA to see which
bases are equivalent in concentration, which of the following would be true?
a. A = G and C = T and A + C = G + T are both true.
b. A = G and C = T
c. A + T = G + C
d. A + C = G + T
e. A = C

Explanation:Erwin Chargaff suggested the rule of the base pairing of DNA structure which is that purine binds pyrimidine or adenine binds thymine and guanine binds cytosine. The composition of adenine and thymine and guanine and cytosine equals 100 percent.

In the given question, since option C shows that A binds T and G binds C and their composition equals 100%, therefore, Option-C is the correct answer.

Thus, Option-C is the correct answer.
