(a)
To determine: The product of the elimination reaction between given reactants.
Interpretation: The product of the elimination reaction between given reactants is to be stated.
Concept introduction: The elimination reaction is the organic reaction in which two substituents are removed from the organic molecule in one step or two steps. The two mechanisms of the elimination reaction are E1 and E2 mechanism.
In E2 mechanism, the elimination takes place in one step.
According to the Zaitsev rule, the formation of

In E2 mechanism, the elimination takes place in one step.
According to the Zaitsev rule, the formation of alkene occurs by the elimination of the hydrogen from the carbon that has less hydrogen.
