\(H_2O\)
\(NH_3\)
\(HBr\)
\(HCl\)
Ammonia \((NH_3)\) can form linear chains or polymers through hydrogen bonding between ammonia molecules, leading to the formation of \(NH_3NH_3NH_3.….\) chains. This hydrogen bonding is responsible for some of the unique properties of ammonia, such as its high boiling and melting points.
So, the correct option is (B): \(NH_3\)
