Solution

The correct options are
C $a (N H_{3}) > a (N_{2}) b u t b (N H_{3}) < b (N_{2})$
D The intermolecular force of attraction between the $N H_{3}$ molecules $>$ the force between $N_{2}$ molecules
The value of $a$ is the measure of the ability of the gas to get liquified easily
So,
$a f o r (N H_{3}) > a f o r (N_{2})$
and $b f o r (N H_{3}) < b f o r (N_{2})$
Also, the intermolecular force of attraction between $N H_{3}$ molecules $>$ the force between $N_{2}$ molecules
