Which of the following sets of quantum numbers is not possible?

Assertion :- In $H$-atom,the energy of $3d$-level is smaller than $4s$-level.
Reason :- In multi-electron species,an orbital with lower value of $(n+\ell)$ has energy smaller than the orbital with larger value of $(n+\ell)$.

Describe the orbitals with the following quantum numbers using $s, p, d, f$ notation:
$(a) n = 1, l = 0$
$(b) n = 3, l = 1$
$(c) n = 4, l = 2$
$(d) n = 4, l = 3$

Match List-$I$ with List-$II$ :

List-$I$ (Quantum numbers)	List-$II$ (Orbital)
$A$. $n = 2, l = 1$	$I$. $3d$
$B$. $n = 4, l = 0$	$II$. $2p$
$C$. $n = 5, l = 3$	$III$. $4s$
$D$. $n = 3, l = 2$	$IV$. $5f$

The number of electrons that can be present in sub-shells having $m_s$ value of $\frac{-1}{2}$,for $n$ up to $3$.
