Given below are two statements, one labelled as Assertion (A) and the other as Reason (R). **Assertion (A):** Bakelite cannot be remelted or reshaped once it is molded and cured. **Reason (R):** Bakelite undergoes extensive cross-linking during molding, forming a three-dimensional network structure that does not soften upon heating. In the context of the above statements, which of the following is correct?

Options:

• A: Both A and R are true and R is the correct explanation of A.
• B: Both A and R are true but R is not the correct explanation of A.
• C: A is true but R is false.
• D: A is false but R is true.
