Reduction of an ester to an alcohol requires a strong reducing agent, such as $\small LiAlH_4$ .

$\small NaBH_4$ is not a strong enough reducing agent for this reaction. Hydrogenation and reaction with zinc would reduce the nitro group to an amino group instead of affecting the carboxylic acid. $\small MeMgBr$ is a Grignard reagent, and would not function as a reducing agent.
