Statement-1: A black hole is an example of a perfectly black body.
Statement-2: A perfectly black body absorbs every kind of radiation incident on it.

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 given in the question, we can break down the reasoning step by step:

### Step 1: Understanding Statement 1
- **Statement 1**: A black hole is an example of a perfectly black body.
- A black hole is an astronomical object with a gravitational pull so strong that nothing, not even light, can escape from it. This characteristic means that it does not reflect or emit any radiation that can be detected, which aligns with the definition of a perfectly black body.

### Step 2: Understanding Statement 2
- **Statement 2**: A perfectly black body absorbs every kind of radiation incident on it.
- By definition, a perfectly black body (or black body) is an idealized physical object that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence. This means it does not reflect any radiation and, therefore, appears black.

### Step 3: Analyzing the Relationship Between the Statements
- Both statements are true:
- A black hole does indeed absorb all radiation that falls into it, making it a perfect black body.
- A perfectly black body, by definition, absorbs all types of radiation incident on it, which is a characteristic that black holes also exhibit.

### Step 4: Conclusion
- Since both statements are correct and Statement 2 provides the correct explanation for Statement 1, we conclude that the correct option is that both statements are true and Statement 2 is the correct explanation for Statement 1.

### Final Answer
Both statements are correct, and Statement 2 is the correct explanation for Statement 1.
