Which of the following sets of quantum numbers is correct for an electron in \( 4 \mathrm{f} \)-orbital?
(a) \( \mathrm{n}=4, l=3, \mathrm{~m}=+4 ; \mathrm{s}=+1 / 2 \)
(b) \( \mathrm{n}=4, l=4, \mathrm{~m}=-4, \mathrm{~s}=-1 / 2 \)
(c) \( \mathrm{n}=4, l=3, \mathrm{~m}=+1, \mathrm{~s}=+1 / 2 \)
(d) \( \mathrm{n}=3, l=2, \mathrm{~m}=-2, \mathrm{~s}=+1 / 2 \)
