${\mathrm{T}}_{\mathrm{e}}=\frac{\mathrm{\pi Re}}{\mathrm{v}}=\frac{{\mathrm{\pi m}}_{\mathrm{e}}}{\mathrm{e}\mathbf{B}}\Rightarrow \mathrm{Tp} > \mathrm{Te}$

${\mathrm{T}}_{\mathrm{p}}=\frac{{\mathrm{\pi m}}_{\mathrm{p}}}{\mathrm{eB}}$

But as it's not mentioned that whether they entered in field together or not (C) and (D) could be right depending on data.

*           The most appropriate answer to this question is (B,D), but because of ambiguity in language, IIT has declared [(B, C), (B, D), (B, C, D)] as correct answer
