Question

Assertion : Boiling point of ethanol is higher than that of propane.
Reason : Molecular mass of ethanol is higher than propane.

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both issertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false
