When a nucleus with atomic number Z and ...

When a nucleus with atomic number `Z` and mass number `A` undergoes a radioactive decay process,
(i) Both `Z` and `A` will decrease, if the process is `alpha` decay
(ii) `Z` will decrease but `A` will not change, if the process is `beta^(+)-`decay
(iii) `Z` will increase but `A` will not change, if the process is `beta-`decay
(iv) `Z` and `a` will remain uncharged, if the prices is `gamma` decay

A

both Z and A will decrease , if the process is `alpha` decay

B

Z will dcrease but A will not change , if the process is `beta^(+)` decay

C

Z will increase but A will not change , if the process is `Beta^(-)` decay

D

Z and A will remain unchanged , if the process is `gamma ` decay
