C. If the assertion is true but the reason is false.
D. If both assertion and reason are false.

Explanation

To solve the question, we need to analyze both the assertion and the reason provided.

### Step 1: Analyze the Assertion
The assertion states: "Planet is a heavenly body revolving round the sun."

- This statement is indeed true. A planet is defined as a celestial body that orbits a star (in our case, the Sun) and has cleared its orbit of other debris. In our solar system, we have eight recognized planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune).

### Step 2: Analyze the Reason
The reason states: "Star is a luminous body made of gaseous."

- This statement is also true. A star is a massive celestial body that emits light and heat due to nuclear fusion reactions occurring in its core. Stars are primarily composed of hydrogen and helium gases.

### Step 3: Determine the Relationship Between Assertion and Reason
Both the assertion and the reason are true statements. However, the question might be asking whether the reason correctly explains the assertion.

- The assertion about planets does not depend on the definition of stars. Therefore, while both statements are correct, the reason does not provide a justification for the assertion.

### Conclusion
- The assertion is true, and the reason is true, but the reason does not explain the assertion.

### Final Answer
- Assertion: True
- Reason: True
- Relationship: The reason does not explain the assertion.
