the correct reaction equation may be

4 p {_{1}}^{1} \to H e {_{2}}^{4} + 2 β^{+} + 2 υ

where

β^{+}

is positron and

υ

is the neutrino (zero rest mass and uncharged)

Solution

The correct options are
A the equation $4 p {_{1}}^{1} \to H e {_{2}}^{4}$ does not satisfy conservation of charge
B the correct reaction equation may be $4 p {_{1}}^{1} \to H e {_{2}}^{4} + 2 β^{+} + 2 υ$ where $β^{+}$ is positron and $υ$ is the neutrino (zero rest mass and uncharged)
C loss of mass in the reaction is $0.028697 a m u$
D the energy equivalent of the mass defect is $26.7 M e V$
Mass defect, $Δ m = 4 m_{H} - m_{H e}$
$= 4 (1.007825) - 4.002603 = 0.028697 u$
$= 0.028697 u \times 932 \frac{M e V}{u} = 26.7 M e V$
