Basic hydrolysis of ethyl acetate gives acetate ion and

The chemical reaction Basic hydrolysis of ethyl acetate is as follows: 

${\mathrm{CH}}_3{\mathrm{COOC}}_2{\mathrm{H}}_5+{\mathrm{H}}_2\mathrm{O}\to {\mathrm{CH}}_3\mathrm{COOH}+{\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}$

The reaction medium above is water, which can be avoided when expressing velocities because it will be in excess. So the speed is given by:

$\text{ Rate }=\mathrm{K}\left[{\mathrm{CH}}_3{\mathrm{COOC}}_2{\mathrm{H}}_5\right]$
IUPAC's name of ${\mathrm{CH}}_3{\mathrm{COOC}}_2{\mathrm{H}}_5$ is Ethyl acetate or Ethyl ethanoate.

Hence, the correct option (A). Ethyl alcohol.
