Assertion : If different gases are filled turn by turn at the same pressure in the discharge tube the discharge in them takes place at the same potential.
Reason : The discharge depends only on the pressure of discharge tube and not on the ionisation potential of gas.

A

If both assertion and reason are ture and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason both are false.

D

If assertion is false but reason is true.

The discharge depends on the pressure of discharge tube and ionisation potential of gas. Since the ionisation potential of different gases are different, hence the dicharge of different gases takes, place at different potential.
