Answer:

A

Explanation:

The DNA is made 4 nitrogenous bases. A (adenine) pairs with T (thymine) and are held by two hydrogen bonds. C (cytosine) pairs with G (guanine) and are held by three hydrogen bonds.

You might wanna remember this by the preposition 'at', which ultimately makes C and G together. Or you might wanna remember it by something like G- C<em>AT</em>.
