(C) $(i)$ The rate of dehydrohalogenation reaction for alkyl groups follows the order: $3^{\circ} > 2^{\circ} > 1^{\circ}$ due to the stability of the transition state leading to the more substituted alkene (Saytzeff rule).$(ii)$ The rate of reaction depends on the leaving group ability of the halogen atom,which follows the order: $I > Br > Cl$.

Which type of rate is observed in dehydrohalogenation ($\beta$-elimination) reaction of alkyl halide?

A
Rate depends on the nature of the alkyl group: $3^{\circ} > 2^{\circ} > 1^{\circ}$
B
Rate depends on the leaving group: $I > Br > Cl$
C
Both $A$ and $B$
D
None of these
