    In the reaction \[_{1}^{2}H+_{1}^{3}H\to _{2}^{4}He+_{0}^{1}n\]. If the tending energies of \[_{1}^{2}H,\text{ }_{1}^{3}H\text{  and  }_{2}^{4}He\] are respectively \[a,\text{ b  and }c\] (in MeV), then the energy (in MeV) released in this reaction is               

    A) \[c+a-b\]

    B) \[c-a-b\]

    C) \[a+b+c\]

    D) \[a+b-c\]

    Correct Answer: B

    Solution :

    [b]  During fusion binding energy of daughter nucleus is always greater than the total energy of the parent nuclei so energy released = c – (a + b) = c – a – b
