Answer:
The correct answer is option C.
Explanation:
On the basis of Chargaff's rule, adenine always base pairs with thymine, and guanine always base pairs with cytosine. This rule is also called complementary base pairing. By following this rule, the DNA polymerase can produce the new strand of DNA easily.
It utilizes the old strand of DNA as a template and produces the new one by opting for the accurate nucleotide on the basis of the template strand. Thus, the correct answer is option C, that is, the base pairs, which make up the center of the molecule of DNA will only match up C with G and A with T.
