Explanation

To determine in which examples of motion a body can be considered approximately a point object, we will analyze each option one by one.

### Step-by-Step Solution:

1. **Option (a): A railway carriage moving without jerks between two stations.**

- **Conclusion:** Yes, it can be considered as a point object.
