Assuming that about \( 20 \mathrm{MeV} \) of energy is released per fusion reaction
\[
{ }_{1} \mathrm{H}^{2}+{ }_{1} \mathrm{H}^{2} \rightarrow{ }_{0} \mathrm{n}^{1}+{ }_{2} \mathrm{He}^{4}
\]
Then the mass of \( { }_{1} \mathrm{H}^{2} \) consumed per day in a fusion reactor of power 1 megawatt will approximately be
(A) \( 0.001 \mathrm{~g} \)
(B) \( 0.1 \mathrm{~g} \)
(C) \( 10.0 \mathrm{~g} \)
(D) \( 1000 \mathrm{~g} \)
