A) formation of antineutrino and \[\alpha -\]particle
B) emission of \[\alpha -\]particle and \[\gamma -\]ray
C) formation of antineutrino and \[\gamma -\]ray
D) formation of antineutrino and positron
Correct Answer: C
Solution :
During the \[\beta -\]emission, a neutron gets converted into a proton along with the formation of antineutrino and electron. \[{{\,}_{0}}{{n}^{1}}\xrightarrow{{}}\,\underset{\text{Proton}}{\mathop{_{1}{{H}^{1}}}}\,+\,\underset{\begin{smallmatrix} \beta \\ \text{particle} \end{smallmatrix}}{\mathop{_{-1}{{e}^{0}}}}\,+\underset{\begin{smallmatrix} Anti \\ neutrino \end{smallmatrix}}{\mathop{{\bar{v}}}}\,+\gamma -ray\]
