Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Boyle's law states "at a constant temperature ( $T$ ), the pressure ( $P$ ) of a given mass (or moles, $n$ ) of any gas varies inversely with the volume ( $V$ )".

According to Boyle's law, $V \propto \frac{1}{P}$

So plot of volume ( $V$ ) versus pressure ( $P$ ) at constant temperature is a hyperbola in the first quadrant.
