(B) Power $P = 5 \, W = 5 \, J/s$. Energy released per fission $E = 200 \, MeV = 200 \times 10^6 \times 1.6 \times 10^{-19} \, J = 3.2 \times 10^{-11} \, J$. Fission rate $R = \frac{P}{E} = \frac{5}{3.2 \times 10^{-11}} \, s^{-1}$. $R = 1.5625 \times 10^{11} \, s^{-1} \approx 1.56 \times 10^{11} \, s^{-1}$.
