For the reactions of alcohols with sodium or potassium metal, the order of reactivity of alcohols is,
Primary > Secondary > Tertiary.
Thus, primary alcohols have maximum reactivity and tertiary alcohols have minimum reactivity.
Because in tertiary alcohol the more alkyl number of alkyl groups decreases acidity.
Option A is correct.
