Assertion : Plane of geostationary satellites always passes through equator.
Reason : Geostationary satellites always lies above Moscow.

Options

A. If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.
B. If both Assertion and Reason are true but Reason is not the correct explantion of Assertion.
C. If Assertion is true, but the Reason is false.
D. If Assertion is false but the Reason is true.

Explanation

To solve the assertion and reason question, we will analyze both statements step by step.

### Step 1: Understand the Assertion
The assertion states that "the plane of geostationary satellites always passes through the equator."

- **Explanation**: Geostationary satellites are satellites that orbit the Earth at the same rotational speed as the Earth. This means they maintain a fixed position relative to the surface of the Earth. For a satellite to remain in a geostationary orbit, it must be positioned directly above the equator. Therefore, the plane of their orbit must indeed pass through the equator.

### Step 2: Understand the Reason
The reason states that "geostationary satellites always lie above Moscow."

- **Explanation**: Moscow is located at a latitude of approximately 55.7558° N, which places it in the northern hemisphere. Geostationary satellites orbit above the equator at a latitude of 0°. Therefore, they cannot be directly above Moscow or any location that is not on the equator. This statement is incorrect.

### Step 3: Conclusion
Based on the analysis:
- The assertion is **correct**: The plane of geostationary satellites does pass through the equator.
- The reason is **incorrect**: Geostationary satellites do not lie above Moscow.

Thus, we conclude that the assertion is true, but the reason is false.

### Final Answer
Assertion is correct, but the reason is incorrect.
