Assertion : Physical adsorption increases with increase in temperature. Reason : Physical adsorption is an endothermic process.A. If both assertion and reason are true and reason is the correct explanation of assertion.B. If both assertion and reason are true but reason is not the correct explanation of assertionC. If assertion is true but reason is falseD. if both assertion and reason are false
