How many orbitals are present in the $4^{th}$ shell with $\ell = 2$?

Given below are two statements:
Statement-$I$: The orbitals having same energy are called as degenerate orbitals.
Statement-$II$: In hydrogen atom,$3p$ and $3d$ orbitals are not degenerate orbitals.
In the light of the above statements,choose the most appropriate answer from the options given.

Which electronic level would allow the hydrogen atom to absorb a photon but not to emit a photon?

What are the values of $n$ and $l$ for the $f$-subshell with the lowest energy?

Consider the following sets of quantum numbers $(n, l, m_l)$:

Set	$(n, l, m_l)$
$A$	$(3, 3, -3)$
$B$	$(3, 2, -2)$
$C$	$(2, 1, +1)$
$D$	$(2, 2, +2)$

The number of correct sets of quantum numbers is $....$.

The two electrons have the following set of quantum numbers:
$P = 3, 2, -2, +1/2$
$Q = 3, 0, 0, +1/2$
Which of the following statements is true?
