Assertion: A spectral line will be seen for a 2px-2py transition. Reason: Energy is released in the form of wave of light when the electron drops from 2px to 2py orbital.

Assertion: A spectral line will be seen for a 2px-2py transition. Reason: Energy is released in the form of wave of light when the electron drops from 2px to 2py orbital. (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 assertion (C) If assertion is true but reason is false (D) If both assertion and reason are false

Both the assertion and reason are false because a spectral line is observed when an electron comes back from the excited state to the ground state in one or more jump. In each jump it comes back to higher energy level to lower energy level corresponding to n = 1, 2, 3, 4...... are called K, L, M, N shells. So, shell must be changed.
