The electron in a hydrogen atom makes a transition \( \mathrm{n}_{1} \longrightarrow \mathrm{n}_{2} \), where \( \mathrm{n}_{1} \& \mathrm{n}_{2} \) are the principal quantum numbers of the two states. Assume the Bohr model to be valid. The time period of the electron in the
\( P \) initial state is eight times that in the final state. The possible values of \( n_{1} \& n_{2} \) are :
(A) \( \mathrm{n}_{1}=4, \mathrm{n}_{2}=2 \)
(B) \( \mathrm{n}_{1}=8, \mathrm{n}_{2}=2 \)
(C) \( \mathrm{n}_{1}=8, \mathrm{n}_{2}=1 \)
(D) \( \mathrm{n}_{1}=6, \mathrm{n}_{2}=3 \)
