Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
At Boyles temperature the compressibility factors of a gas approaches unity.
When $Z = 1$ over wide range of pressures, $P V = n R T$ .
This is possible when both a and b have negligible values so that $(P + \frac{a}{V^{2}}) = P a n d (V - b) = V$ .
Hence, at Boyle's temperature the real gases obey ideal gas laws.
Thus, Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
