Solution

The correct option is A adding acetic acid with $H_{2} S O_{4}$ to it which will form ester
Alcohols are weaker acid than water and they react with strong reactive metals like sodium to form alkoxides ${R O}^{-} {N a}^{+}$
To form an ester from alcohol and carboxylic acid the reaction is Fischer esterification refluxed with a catalyst of conc.sulfuric acid.
$R O H + R^{'} C O O H \to R^{'} C O O R + H_{2} O$
