Assertion : Gases become denser at high pressure .Reason : At high pressures , gases deviate from Boyle's law .

Answer»

<P>If both assertion and reason are true and reason is the correct explanation of assertion .
If both assertion and reason are true but reason is notthe correct explanation of assertion .
If assertion is true but reason is FALSE .
If both assertion and reason are false .
