Best answer
Correct option is (b) Dehydrating agent

Easiest explanation: Concentrated H2SO4 is the catalyst in the esterification of alcohols, which acts a protonating and dehydrating agent. The reaction is reversible and is shifted in the forward direction by the removal of water as soon as it is formed.
