H2O because H bonding strength depends on the electronegativity difference between H and other atom (F,O,N, etc.). Greater the electronegativity difference greater will be the strength of H bonding.

CO is isoelectronic with (a) NO+ (b) N2 (c) SnCl2 (d) N02

CO is isoelectronic with both NO+ and N2 because both have 14 e- which are equal to CO e-s . For isoelectronic specie we see total e-s present in specie not only valence e-s.
