Answer:

B

Explanation:

This is because of the base pairing rule in DNA. Guanine (G) pairs with Cytosine(C) while Adenine(A) pairs with Thiamine (T). Therefore, the amount of G will relatively be generally equal l to that of C while that of A will be generally equal to that of T. The amount of the complimentary base pairs will, therefore, be equal.
