Haloalkanes and Haloarenes

The major product formed in the dehydrohalogenation reaction of 2-bromopentane is pent-2-ene. This product formation is based on:

A.Saytzeff's rule✓
B.Hund's rule
C.Hofmann rule
D.Hückel's rule

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
