Guanine

Detailed explanation-1: -Adenine and thymine are connected by two hydrogen bonds, and cytosine and guanine are connected by three hydrogen bonds.
Detailed explanation-2: -Note: Cytosine can form three hydrogen bonds with guanine, and adenine can form two hydrogen bonds with thymine. In simple words, C bonds with G and A bonds with T. This is called complementary base pairing because each base can only bond with a specific base partner.
Detailed explanation-3: -It is a truth universally acknowledged that a guanine–cytosine (GC) base pair has three hydrogen bonds whereas adenine–thymine (AT) has two.
Detailed explanation-4: -Correct answer: Cytosine and guanine, when base paired, have three hydrogen bonds between them. Adenine and thymine only have two.
