Explanation:
Detailed explanation-1: -The correct option is C The complementary DNA strand of the sequence ATGC will be TACG.
Detailed explanation-2: -During DNA replication, each of the two strands that make up the double helix serves as a template from which new strands are copied. The new strand will be complementary to the parental or “old” strand. Each new double strand consists of one parental strand and one new daughter strand.
Detailed explanation-3: -Replication relies on complementary base pairing, that is the principle explained by Chargaff’s rules: adenine (A) always bonds with thymine (T) and cytosine (C) always bonds with guanine (G).
