From the famous Einstein mass-energy equivalence relation, energy equivalent to one atomic mass unit $$u$$ is required, given $$1u=1.6605\times10^{-27}\,\mathrm{kg}$$ and $$c=2.9979\times10^8\,\mathrm{m/s}$$. It is close to

A

$$931\,\mathrm{J}$$

B

$$931\,\mathrm{eV}$$

C

$$931\,\mathrm{MeV}$$

D

$$931\,\mathrm{keV}$$
