Solution

The correct option is B $β^{-}$ decay
It is $β^{-}$ -decay.
In $β^{-}$ decay, the weak interaction converts an atomic nucleus into a nucleus with atomic number increased by one, while emitting an electron $(e -)$ and an electron antineutrino (νe). $β^{-}$ decay generally occurs in neutron rich nuclei.
