Elimination reaction of 2 – bromo pentane to form pent – 2 – ene is

a) $\beta -$Elimination reaction

b) follows zaitsev rule

c) De hydro halogenation reaction

d) De hydration reaction

This reaction is an example of β-elimination.Hydrogen is removed from β-carbon and halogen from α-carbon, hence dehydrohalogenation reaction.

Pent-2-ene is major product known as Saytzeff's product and it is more stable alkene than Pent-1-ene.
 

Generally, in E2​ reaction Zaitsev alkene is formed as a major product (more stable alkene).
