Mx and My denote the atomic masses of the parent and the daughter nuclei respectively in a radioactive decay.

M_x and M_y denote the atomic masses of the parent and the daughter nuclei respectively in a radioactive decay. The Q-value for a β ^– decay is Q₁ and that for a β ⁺ decay is Q₂. If me denotes the mass of an electron, then which of the following statements is correct?

(a) Q₁ = (M_x – M_y) c² and Q₂ = (M_x – M_y – 2m_e)c²

(b) Q₁ = (M_x – M_y) c² and Q₂ = (M_x – M_y )c²

(c) Q₁ = (M_x – M_y – 2m_e) c² and Q₂ = (M_x – M_y +2 m_e)c²

(d) Q₁ = (M_x – M_y + 2m_e) c² and Q₂= (M_x – M_y +2 m_e)c²
