Solution

The correct option is A Ether, ester
$1.$ Ethyl alcohol gives diethyl ether by acid catalysed condensation reaction.
$2 C_{2} H_{5} O H c o n c . H_{2} S O_{4} - ------ \to 140^{o} C C_{2} H_{5} O C_{2} H_{5} (B) + H_{2} O$
$2.$ Action of carbon monoxide on diethyl ether is shown in the following reaction.
$C_{2} H_{5} - O - C_{2} H_{5} + C O B F_{3} / 150^{o} C - ------ \to 900 atm C_{2} H_{5} C O O C_{2} H_{5} (C)$
Hence, the functional groups in $B$ and $C$ are ether and ester respectively.
