0When an electron in hydrogen atom is excited, from its 4th to 5 th stationary orbit, the change in angular momentum of electron is (Planck's constant: \( h=6.6 \times 10^{-34} \mathrm{~J}-\mathrm{s} \) )
(A) \( 4.16 \times 10^{-34} \mathrm{~J}-\mathrm{s} \)
(B) \( 3.32 \times 10^{-34} \mathrm{~J}-\mathrm{s} \)
(C) \( 1.05 \times 10^{-34} \mathrm{~J}-\mathrm{s} \)
(D) \( 2.08 \times 10^{-34} \mathrm{~J}-\mathrm{s} \)
