Explanation / Answer

In given all of the following pair, the following pairs of species that can interact via ion-dipole forces:

In this, one species should be ion and other should be polar (act as dipole), therefore:

Cs+ (ion) and H2O (polar) = Ion-dipole interaction

CH3OH (polar) and NO3-(ion) = Ion-dipole interaction

Mg2+(ion) and CH3Cl (polar) = Ion-dipole interaction

Na+ and Br- = Ionic interaction

H2O (Polar) and CH3OH (Polar) = dipole- dipole interaction = Hydrogen bond

CN- (ion) and C2H6 (non-polar) = dispersion
