Solution

The correct option is A $N a C l$
Both C and Cl are non-metal. As two non-metal atoms form a covalent bond, C-Cl covalent bond is formed. There are 4 C-Cl bonds in CCl₄ molecule.

Although C-Cl bond is polar, CCl₄ molecule is non-polar because CCl₄ is a symmetrical molecule and the dipole moments of the four C-Cl bonds cancel each other.

The same is with CH $_{4}$ .

The classic case of ionic bonding, the sodium chloride molecule forms by the ionization of sodium and chlorine atoms and the attraction of the resulting ions.

Hence, A is the correct option.
