Solution

The correct option is A
volatile in nature

The equation of the chemical reaction to produce nitric acid is given below

$K N O_{3} + H_{2} S O_{4} \to K H S O_{4} + H N O_{3}$

Nitric acid can easily evaporate at normal temperatures. Hence the acid vapours that come out of the preparation are cooled and condensed using cold water. Therefore we can say that nitric acid is volatile in nature.
