In the reaction, ₁H² + ₁H³ → ₂He⁴ + ₀n¹, if the binding energies of ₁H², ₁H³ and ₂He⁴ are respectively, a, b and c (in MeV), then the energy (in MeV) released in this reaction is

1. a + b + c
2. a + b – c
3. c – a – b
4. c + a – b

Correct Option: C

₁H² and ₁H³ requires a and b amount of energies for their nucleons to be separated.
₂He⁴ releases c amount of energy in its formation i.e., in assembling the nucleons as nucleus.
Hence, Energy released =c – (a + b) = c – a – b
