Two Deuterium Nuclei, H, Fuse to Produce a Helium

Two deuterium nuclei, H, fuse to produce a helium nucleus,
H, and a neutron. A neutral deuterium atom has a mass of 2.014102 u; a neutral helium atom has a mass of 3.016030 u; a neutral hydrogen atom has a mass of 1.007825 u; a neutron has a mass of 1.008665 u; and a proton has a mass of 1.007276 u. How much energy is released in the process? (1 u = 931.494 MeV/c²)

A) 3.27 MeV
B) 3.57 MeV
C) 4.00 MeV
D) 4.50 MeV
E) 5.68 MeV
