A) fission
B) \[\beta \]-decay
C) \[\alpha \]-decay
D) fusion
Correct Answer: B
Solution :
[b] \[-{{1}^{{{e}^{0}}}}\] is known as \[{{\beta }^{-}}\] particle & \[\overline{v}\] is known as antineutrino. Since in this reaction \[\overline{v}\] is emitted with \[-{{1}^{{{e}^{0}}}}\] (\[{{\beta }^{-}}\] particle or electron), so it is known as \[\beta \]-decay.
