Vedclass · Answer

(A) Nuclear fusion is a process where lighter nuclei combine to form a heavier nucleus.According to Einstein's mass-energy equivalence principle,$E = \Delta m c^2$,where $\Delta m$ is the mass defect.For energy to be released,the final mass of the product must be less than the initial mass of the reactants.In the fusion reaction $^2_1H + ^2_1H ightarrow ^4_2He + 	ext{Energy}$,the mass of the resulting helium nucleus $(M_{He})$ is less than the sum of the masses of the two deuteron nuclei $(2m_d)$.This mass difference $(\Delta m = 2m_d - M_{He})$ is converted into energy.
