The correct answer is: If both assertion and reason are true and reason is the correct explanation of assertion.
Greater the number of $\mathrm{H}$-atoms present on the carbon atoms $\alpha$ to unsaturation the more resonating forms are possible due to hyperconjugation and thus greater is the stability of carbonium ion.
