When acetic acid is subjected to reaction with NaOH and CaO, decarboxylation occurs and \mathrm{CH_4} is formed. Hence, P is \mathrm{CH_4}

When acetic acid is subjected to Kolbe's Electrolysis, decarboxylation and coupling occurs and \mathrm{C_2H_6} is formed. Hence, Q is \mathrm{C_2H_6}

Thus, the difference in molar mass of P and Q is 14 g/mol.

Therefore, the correct answer is Option (3)
