Assertion (A) : A spectral line will be seen for `2p,-2p` transition
Reason (R ) : Energy is raleased in the form of wave of light when the electron drops from `2p_(x)` , to `2p_(y)` orbital.

Options

A. If both (A) and (R ) correct and (R ) is the correct explanation for (A)
B. If both (A) and (R ) correct and (R ) is the correct explanation for (A)
C. If (A) is correct but (R ) is incorrect
D. If both (A) and (R ) are incorrect

Explanation

To solve the question, we need to analyze both the assertion and the reason provided.

### Step 1: Analyze the Assertion
The assertion states that a spectral line will be seen for a `2p` to `-2p` transition. In atomic physics, spectral lines are produced when electrons transition between different energy levels.

- The `2p` orbitals (2px, 2py, 2pz) are degenerate, meaning they have the same energy level.
- A transition between these orbitals (like from `2px` to `2py`) does not involve a change in energy because they are at the same energy level.
