Assertion:- Bakelite is a thermosetting polymer.

Reason:- It has highly branched structure.

View answer and explanation

Correct option: B

If both assertion & reason true but reason is not a correct explanation of the assertion

Option B (If both assertion & reason true but reason is not a correct explanation of the assertion) is correct because Bakelite is thermosetting and has a branched structure, but the branching isn't the *direct* cause of it being thermosetting.
