Assertion : Bakelite is hard and cannot be remoulded and recycled.
Reason : Bakelite is a thermoplastic polymer.

Options

A. Assertion and reason both are correct statements and reason is correct explanation for assertion.
B. Assertion and reason both are correct statements but reason is not correct explanation for assertion.
C. Assertion is correct statement but reason is wrong statement.
D. Assertion is wrong statement but reason is correct statement.

Explanation

To analyze the given assertion and reason, we will break it down step by step.

### Step 1: Understand the Assertion
The assertion states that "Bakelite is hard and cannot be remoulded and recycled."
- Bakelite is indeed a hard material.
- It is a type of polymer known for its durability and resistance to heat.
- Importantly, Bakelite is classified as a thermosetting polymer, which means that once it is set, it cannot be reshaped or remoulded.

### Step 2: Understand the Reason
The reason states that "Bakelite is a thermoplastic polymer."
- This statement is incorrect. Bakelite is not a thermoplastic; it is a thermosetting polymer.
- Thermoplastics can be remoulded and recycled upon heating, while thermosetting polymers cannot.

### Step 3: Conclusion
- The assertion is true: Bakelite is hard and cannot be remoulded or recycled.
- The reason is false: Bakelite is not a thermoplastic polymer; it is a thermosetting polymer.

### Final Answer
Thus, the correct conclusion is that the assertion is true, but the reason is false.
