Solution

The correct option is A Both Assertion and Reason are correct and the Reason is the correct explanation of Assertion
p-orbitals are degenerate orbitals. They have same energy level. The energy difference between $p_{x}$ and $p_{y}$ orbitals is zero.
Hence, transition of electron between $p_{x}$ and $p_{y}$ would not lead to an spectral line.
Thus, Both Statement and Explanation are correct and Explanation is the correct explanation for Statement.
