In the following questions , a statement of assertion (A) is followed by a statement of reason (R).
A. The value of van der Waals constant `a` smaller for `O_2` than for `H_2O`.
R. Molar mass of `O_2` is greater than that of `H_2O`.

A

If both Assertion & Reason are true and the reason is the correct explanation of the assertion, then mark (1).

B

If both Assertion & Reason are true but the reason is not the correct explanation of the assertion, then mark (2).

C
