(C) Lewis acid is defined as an electron pair acceptor.$NH_3$ has a lone pair on nitrogen and acts as a Lewis base.$H_2O$ has lone pairs on oxygen and acts as a Lewis base.$HCl$ is a Bronsted-Lowry acid but does not have an incomplete octet to accept an electron pair in the Lewis sense.$SO_2$ has a central sulfur atom with vacant $d$-orbitals and can accept an electron pair,making it a Lewis acid.
