Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
$N H_{3}$ ha boiling point $240^{o} K (- 33^{o} C)$ . It exists as gas under normal conditions. Pressure is directly proportional to boiling point. If we apply high pressure, then boiling point will be high. So it exists in liquid form.
$N H_{3}$ and water forms a homogeneous solution and water has boiling point of $393^{o} L$ . So it doesn't evaporate easily. So it remains as solution at room temperature.
Reason doesn't explain assertion.
