Answer:
The correct statement are 1,2 and 4.
Step-by-step explanation:
Beta minus decay: In this process, a neutron gets converted into a proton and an electron releasing a beta-particle. Along with release in energy.
The beta particle released carries a charge of -1 units.

Beta plus decay: In this process, a proton gets converted to neutron and an electron neutrino and releases positron particles (beta particles with positive charge) .Along with release in energy
This particle carries a charge of +1 units.

The correct statement are 1,2 and 4.
