It's always pair with A-T and C-G, I just learn it about this like last month

Answer: The correct answer is-

Adenine (A) pairs with Thymine (T) and Guanine (G) pairs with cytosine (C).

Explanation:

DNA replication is a process of formation of two molecules of DNA from a single DNA molecule, which is double stranded.

During this process, the two strands of original DNA molecule are initially separated (unzipped) and act like template strand.

Using the template strand, enzyme DNA polymerase adds dNTP (deoxyribonucleoside triphosphate, which is monomer of DNA) in the direction 5' to 3' (which is antiparallel to the direction of template strands).

The dNTPs are added according to Watson and Crick base pairing, which is-

Nitrogenous base A pairs with T through two bonds of hydrogen, G pairs with C through three bonds of hydrogen.
