Assertion (A): Wood, paper and leather are bio-degradable wastes.
Reasoning (R): They cannot be broken down by biological or microbial action. Choose the correct option

Options

A. A is correct and R is the correct explanation of A.
B. A is correct and R is not the correct explanation of A.
C. A is correct and R is wrong.
D. A is wrong and R is correct.

Answer

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

### Step 1: Understand the Assertion
The assertion states: "Wood, paper, and leather are biodegradable wastes."
- Biodegradable wastes are materials that can be broken down by biological or microbial action.
- Wood, paper, and leather are indeed materials that can decompose through the action of microorganisms.

### Step 2: Understand the Reasoning
The reasoning states: "They cannot be broken down by biological or microbial action."
- This statement contradicts the assertion. If wood, paper, and leather are biodegradable, then they can be broken down by biological or microbial action.

### Step 3: Evaluate the Correctness of Assertion and Reasoning
- The assertion is **correct** because wood, paper, and leather are biodegradable.
- The reasoning is **incorrect** because it claims that these materials cannot be broken down by biological or microbial action, which is false.

### Step 4: Choose the Correct Option
Based on the analysis:
- The assertion is correct, but the reasoning is incorrect.
- Therefore, the correct option is: "The assertion is correct and the reason is wrong."

### Final Answer
The correct option is: **Third - The assertion is correct and the reason is wrong.**
