c
As charges of the ions increases or their sizes decreases the lattice energy increases resulting in higher melting point and greater hardness.
As charges of the ions increases or their sizes decreases the lattice energy increases resulting in higher melting point and greater hardness.
Amongst sodium halides $NaF$ has the maximum lattice energy so it has the highest melting point. As $F$-has the smallest size.
