The atom that results from beta decay has an atomic number 1 more than the original one.
Option c
Explanation:
Beta decay is the process of radioactive disintegration by which unstable atomic nuclei dissipate excess energy and undergo a change of unit of positive charge without changing its mass number.
For eg: The β-decay of Hydrogen-2 which has the atomic number of 1 and mass number of 2 decays to helium-2 having an atomic number of 2 and mass number of 2.
