Which of the following statement is correct?

Options

A. Moon is the only natural satellite of Earth
B. The time period of the moon is approx 27.3 days
C. The time period of moon is roughly equal to the rotational period of moon about its own axis
D. All of the above

Explanation

To determine which statement is correct regarding the Moon and its relationship with Earth, let's analyze the statements step by step.

### Step-by-Step Solution:

1. **Identify the Statements**:
- The first statement claims that the Moon is the only natural satellite of Earth.
- The second statement mentions that the time period of the Moon is approximately 27.3 days.
- The third statement asserts that the time period of the Moon is roughly equal to its rotational period about its own axis.

2. **Evaluate the First Statement**:
- The Moon is indeed the only natural satellite of Earth. This statement is correct.

3. **Evaluate the Second Statement**:
- The Moon takes about 27.3 days to complete one orbit around the Earth. This is known as the sidereal month. This statement is also correct.

4. **Evaluate the Third Statement**:
- The Moon's rotational period (the time it takes to spin once on its axis) is approximately 27.3 days, which is the same as its orbital period around Earth. This statement is also correct.

5. **Conclusion**:
- Since all three statements are correct, the correct answer is that all the above statements are true.

### Final Answer:
The correct option is **4. All the above**.
