A
Adenine-GuanineCytosine-Thymine/Uracil
B
Adenine-CytosineGuanine-Thymine/ Uracil
C
Adenine-Thymine/ UracilCytosine-Guanine
D
Adenine-UracilCytosine-Guanine/ Thymine
Explanation: 

Detailed explanation-1: -Under normal circumstances, the nitrogen-containing bases adenine (A) and thymine (T) pair together, and cytosine (C) and guanine (G) pair together.

Detailed explanation-2: -Final answer: Adenine-Thymine is the correct base pairing for DNA molecules.

Detailed explanation-3: -Base Pair The two strands are held together by hydrogen bonds between pairs of bases: adenine pairs with thymine, and cytosine pairs with guanine.

Detailed explanation-4: -Adenine always pairs with thymine, and cytosine always pairs with guanine.
