n a sample of radioactive nuclide

Options

A. a nucleus emits, `alpha,beta` radiations simultaneously.
B. only `alpha,beta` can be emitted simultaneously by a nucleus.
C. `alpha,beta,gamma` may be obtained simultaneously from the sample
D. all the three `alpha,beta,gamma` one after other will obtained from a nucleus

Explanation

To solve the question regarding the decay of a radioactive nuclide, we will analyze the possible decay processes that can occur in a radioactive sample.

### Step-by-Step Solution:

1. **Understanding Radioactive Decay**:
Radioactive nuclides can undergo different types of decay processes: alpha decay, beta decay, and gamma decay. Each type of decay has distinct characteristics and occurs under specific conditions.

2. **Types of Decay**:
