Assertion: The value of van der Waals constant a is larger for ammonia than for nitrogen.
Reason: Hydrogen bonding is present in ammonia.

A

If both (`A`) and (`R`) are correct and (`R`) is the correct explanation of (`A`).

B

If both (`A`) and (`R`) are correct, but (`R`) is not the correct explanation of (`A`).

C

If (`A`) is correct, but (`R`) is incorrect.

D

If (`A`) is incorrect, but (`R`) is correct.
