a neutron in the nucleus decays emitting an electron

(C) The process of $\beta^{-}$-decay is represented by the following nuclear reaction:${ }_{Z}^{A} X \longrightarrow{ }_{Z+1}^{A} Y + e^{-} + \bar{\nu} + Q$In this process,a neutron inside the nucleus transforms into a proton,emitting an electron $(e^{-})$ and an anti-neutrino $(\bar{\nu})$.Therefore,the correct statement is that a neutron in the nucleus decays,emitting an electron.
