What are the total number of electrons present in $s$ and $p$ orbitals respectively in the ground state of an argon atom $(Z = 18)$?

Which of the following orbitals is not possible (in $f$)?

The extra stability of half-filled subshells is due to:

$(B)$ Smaller coulombic repulsion energy
$(C)$ The presence of electrons with the same spin in non-degenerate orbitals
$(D)$ Larger exchange energy
$(E)$ Relatively smaller shielding of electrons by one another
