@Matthew16 I suggest you explain rather than blurt out answers, especially when it's the \(\sf \color{red}{wrong}\) answer.

Answer 3

Do you know about complementary base pairing?
Like cytosine (C) can form three hydrogen bonds with guanine (G) , and adenine (A) can form two hydrogen bonds with thymine (T).
Or, more simply, C bonds with G and A bonds with T.
It's called complementary base pairing because each base can only bond with a specific base partner. The structures complement each other, in a way, like a lock and a key. You need a specific key to unlock the lock right?
So similarly, C will only bond with G and A will only bond with T in DNA. Because of complementary base pairing, the hydrogen-bonded nitrogenous bases are often referred to as "base pairs".
