Statement-1: Moon cannot be used as a satellite for communication.
Statement-2: Moon doesn't move in the equatorial plane of the earth.

Options

A. Statement-1 is true, statement-2 is true: Statement-2 is a correct explanation for statement-1
B. Statement-1 is true, Statement-2 is true, Statement-2 is not a correct explanation for Statement-1
C. Statement-1 is true, Statement-2 is false.
D. Statement-1 is false, Statement-2 is true.

Answer

To analyze the statements provided in the question, we will evaluate each statement independently and then assess the relationship between them.

### Step 1: Evaluate Statement 1
**Statement 1:** Moon cannot be used as a satellite for communication.

- The Moon is indeed very far from the Earth, at an average distance of about 384,400 km.
- Communication via the Moon would involve significant time delays due to the distance.
- Additionally, the cost of establishing and maintaining communication systems with the Moon would be much higher compared to using artificial satellites that are much closer to Earth.

**Conclusion:** Statement 1 is true.

### Step 2: Evaluate Statement 2
**Statement 2:** Moon doesn't move in the equatorial plane of the Earth.

- The Moon's orbit is inclined at an angle of about 5 degrees to the Earth's equatorial plane.
- This means that the Moon does not follow the same plane as the Earth's equator, which can complicate communication systems that rely on satellites being in the same plane for optimal signal transmission.

**Conclusion:** Statement 2 is also true.

### Step 3: Determine the Relationship Between the Statements
- Statement 2 provides a reason why the Moon cannot be effectively used for communication as a satellite.
- Since the Moon's orbit is not aligned with the equatorial plane, it would not be able to maintain a stable position relative to the Earth, which is essential for communication satellites.

**Conclusion:** Statement 2 is the correct explanation of Statement 1.

### Final Conclusion
Both statements are true, and Statement 2 explains why Statement 1 is true. Therefore, the answer is that both statements are true, and Statement 2 is the correct explanation of Statement 1.
