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 Zand A will decrease if the process is `alpha` decay
B
Z will decrease but A will not change the process is `beta^(+)` decay
C
Z will increase but A will not change the process is `beta^(-)` decay
D
Z and A will remain unchanged the process is `gamma` decay
