(B) The mass of a proton $(m_p)$ is approximately $1.672 \times 10^{-27} \ kg$. The mass of an electron $(m_e)$ is approximately $9.109 \times 10^{-31} \ kg$. The ratio $m_p / m_e$ is calculated as: $m_p / m_e \approx (1.672 \times 10^{-27}) / (9.109 \times 10^{-31}) \approx 1836 \approx 1.8 \times 10^3$. Therefore,the correct option is $(B)$.
