Solution

The correct option is A
Adenine-Thymine

The correct option is A.
Explanation of correct option:
Option A
DNA molecules consist of four nucleotides - adenine, guanine, cytosine, and thymine.
Base pairing in the presence of hydrogen bonding.
Adenine - Thymine
Guanine - Cytosine
Explanation of incorrect option:
Option B
Thymine pairs with adenine by using two hydrogen bonds.
Option C
Cytosine pairs with guanine by using three hydrogen bonds.
Option D
In RNA, adenine always pairs with uracil.
Final answer: Adenine-Thymine is the correct base pairing for DNA molecules.
