A man is sitting inside a moving train and observes the stationary objects outside of the train. Then choose the single correct choice from the following statements`-`

Options

A. all stationary objects outside the train will move with same velocity in opposite direction of the train with respect to the man.
B. stationary objects near the train will move with greater velocity & object far from train will move with lesser velocity with respect to the man.
C. large objects like moon or mountains will move with same velocity as that of the train
D. all of these

Explanation

To solve the problem, we need to analyze the situation where a man is sitting inside a moving train and observing stationary objects outside the train. We will use the concept of relative velocity to understand the motion of the objects from the man's perspective.

### Step-by-Step Solution:

1. **Identify the Frame of Reference**:
- The man is inside a moving train. We need to consider the train as our frame of reference.

2. **Define Velocities**:
- Let \( V_m \) be the velocity of the man (which is the same as the velocity of the train, \( V_t \)).
- The stationary objects outside the train have a velocity of \( V_o = 0 \) (since they are stationary).

3. **Apply the Relative Velocity Concept**:
- The relative velocity of the stationary objects with respect to the man is given by:
\[ V_{om} = V_o - V_m \]
- Substituting the values, we get:
\[ V_{om} = 0 - V_t = -V_t \]
- This means that from the man’s perspective, the stationary objects appear to be moving with a velocity equal to the velocity of the train but in the opposite direction.

4. **Evaluate the Statements**:
- Now we can analyze the provided statements:
- **Statement 1**: All stationary objects outside the train will move with the same velocity in the opposite direction of the train with respect to the man.
- This statement is **correct** as derived.
- **Statement 2**: Stationary objects near the train will move with greater velocity.
- This statement is **incorrect**.
- **Statement 3**: Large objects like the moon or mountains will move with the same velocity as that of the train.
- This statement is **incorrect**.
- **Statement 4**: All of these.
- This statement is **incorrect**.

5. **Conclusion**:
- The only correct statement is **Statement 1**.

### Final Answer:
The correct choice is: **All stationary objects outside the train will move with the same velocity in the opposite direction of the train with respect to the man.**
