A. I only

参考答案: C
本题详细解析:
Explanation: A change in the proton composition of a nucleus is needed to label it as a different nucleus. Both alpha (α) and Beta (β) decay change the proton and neutron number of the parent nucleus therefore a different daughter will be produced. On the other hand, gamma (γ) decay involves only the loss of excess energy, not the change in nucleon composition therefore the daughter is the same as the parent. Therefore, the answer is C.
