Elimination reaction of 2-Bromo-pentane to form pent-2-ene is:(a) $\beta$ -Elimination reaction(b) Follows Zaitsev rule(c) Dehydrohalogenation reaction(d) Dehydration reaction

The reaction of 2-bromopentane to pent-2-ene:It is a $\beta$ -elimination because $H$ is removed from the $\beta$ -carbon.It follows Zaitsev's rule because the more substituted alkene (pent-2-ene) is the major product.It is a dehydrohalogenation because $H$ and $Br$ are removed.It is not dehydration (removal of water).
