Read the given statements and select the correct option.
Statement 1 : When a person walk on a rough surface, the frictional force exerted by the surface on the person is opposite to the direction of motion.
Statement 2: Friction always acts opposite to the direction of motion.

Options

A. Both statements 1 and 2 are true and statement 2 is the correct explanation of statement 1
B. Both statements 1 and 2 are true but statement 2 is not the correct explanation of statement 1.
C. Statement 1 is true but statement 2 is false
D. Both the statements 1 and 2 are false.

Explanation

To solve the question, we need to analyze the two statements provided:

**Statement 1:** When a person walks on a rough surface, the frictional force exerted by the surface on the person is opposite to the direction of motion.

**Statement 2:** Friction always acts opposite to the direction of motion.

### Step-by-Step Solution:

1. **Understanding Statement 1:**
- When a person walks on a rough surface, they exert a force backward against the ground with their foot.
- Due to Newton's third law, the ground exerts an equal and opposite force (friction) on the person.
- This frictional force acts in the direction of the person's motion, allowing them to move forward.
- Therefore, **Statement 1 is correct** because the frictional force acts in the direction opposite to the backward push of the foot, which is consistent with the direction of motion.

2. **Understanding Statement 2:**
- The statement claims that friction always acts opposite to the direction of motion.
- This is generally true; however, it is important to clarify that friction acts opposite to the direction of relative motion between two surfaces in contact.
- For example, if an object is sliding on a surface, the friction force will act in the direction opposite to the sliding motion.
- Therefore, **Statement 2 is also correct** as it describes the nature of friction accurately.

3. **Conclusion:**
- Both statements are correct based on the principles of friction and motion.
- Thus, the correct option is that both statements are true.

### Final Answer:
Both Statement 1 and Statement 2 are correct.
