A

both the isobars are stable

B

`Zn^(64)` is radioactive , decaying to `Cu^(64)` through `beta`-decay

C

`Cu^(64)`is radioactive , decaying to `Zn^(64)` through `gamma`-decay

D

`Cu^(64)`is radioactive , decaying to `Zn^(64)` through `beta`-decay

Text Solution

Verified by Experts

The correct Answer is:
d
By the conservation of charge and nucleons, only potential is feasible.
