Vedclass · Answer

(D) Degenerate orbitals are those that have the same energy level.In a hydrogen-like atom or in the absence of an external field,orbitals belonging to the same subshell (same $n$ and $l$ values) are degenerate.For the set $2p_x, 2p_y, 2p_z$,all three orbitals have the same principal quantum number $(n = 2)$ and the same azimuthal quantum number $(l = 1)$,meaning they belong to the same $2p$ subshell.Therefore,they have the same energy and are degenerate.
