Answer:
Correct answer - B
Step-by-step explanation:
Radioactive decay is the process of in which an unstable atomic nucleus loses energy by emitting ionize particles and radiation transforming the parent nuclide atom into a different atom called daughter nuclide.
Nuclear equation that show the atomic number and mass number of every particle which are involved in the radioactive decay.
The given nuclear reaction is as follows.
Therefore,Correct answer - B
