Solution

The correct option is C If assertion is true but reason is false.
Bakelite is a thermosetting polymer, and thermosetting polymers cannot be reused.

When heated, thermosetting polymers form cross-links between their molecular chains which makes them retain their shape and so cannot be remoulded.
