Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
At Boyle's temperature, a real gas behaves as ideal gas for a wide range of temperature and pressure.
This is because van der Waal constant $^{'} a^{'}$ and $b$ compensate each other at Boyle's temperature.
Hence, the value of the compressibility factor is $Z$ .
