Cleck up the onlycorrect statements in the following :

Options

A. A body having a constant velocty still can have varying speed.
B. A body having a constant speed can have varying velocity.
C. A body having constant speed can have an acceleration.
D. If body having accleration are in the same direction, then distance is equal to displacement.

Explanation

To solve the problem, we need to evaluate each statement provided and determine which ones are correct. Let's analyze each statement step by step.

### Step-by-Step Solution:

1. **Statement 1: A body having a constant velocity still can have a varying speed.**
- **Analysis**: Velocity is a vector quantity that includes both magnitude and direction. If a body has a constant velocity, it means both the magnitude and direction are constant. If the speed (magnitude of velocity) varies, then the velocity itself cannot be constant. Therefore, this statement is **incorrect**.

2. **Statement 2: A body having a constant speed can have a varying velocity.**
- **Analysis**: A body can indeed have a constant speed while changing direction. A prime example of this is uniform circular motion, where the speed remains constant but the direction of the velocity vector changes continuously. Thus, this statement is **correct**.

3. **Statement 3: A body having constant speed can have acceleration.**
- **Analysis**: In uniform circular motion, a body can maintain a constant speed while experiencing acceleration due to the change in direction. The acceleration is directed towards the center of the circular path (centripetal acceleration). Therefore, this statement is **correct**.

4. **Statement 4: If a body having acceleration is in the same direction, then distance is equal to displacement.**
- **Analysis**: If a body accelerates in the same direction without changing direction, it moves in a straight line. In such cases, the distance traveled will be equal to the displacement since both are measured in the same direction. Hence, this statement is **correct**.

### Conclusion:
The correct statements are **2, 3, and 4**.
