Solution

Organic compound A is a sweet-smelling compound ethyl acetate commonly known as esters.
Esters on hydrolyses in the presence of dilute sulphuric acid give carboxylic acid and alcohol.
A balanced chemical reaction illustrating the process is given as
$C H_{3} C O O C H_{2} C H_{3} \overset{d i l . H_{2} S O_{4}}{\to} C H_{3} C O O H + C H_{3} C H_{2} O H$
Ethyl acetate Ethanoic acid Ethanol
$B$ $C$
Hence, A is Ethyl acetate, which on hydrolysis gives Ethanoic Acid ( $B$ ) and Ethanol ( $C$ ).
