Solution

The correct option is D Both Assertion and Reason are incorrect
Assertion
Compressibility factor (Z) for non-ideal gases may be either greater than 1 (positive deviation from ideal behavior) or less than 1 (negative deviation from ideal behavior). It may also be close to 1 (ideal behavior). At Boyle's temperature $Z = 1$ .
Reason
Non-ideal gases always exert lower pressure expected due to presence of inter-molecular attractive forces.

Both Assertion and Reason are incorrect.
