Thermoplastic polymers can be reshaped by heating. So it is not deformed permanently. On the other hand thermosetting plastic has a cross linkage structure, so they cannot be reshaped once moulded.
So correct answer is themosetting plastic.
So correct answer is themosetting plastic.

Thermosetting plastic because the do not regain shape.

The thermoset polymers are highly cross linked polymer. So when it heated it cross link become damage or destroyed permanently so it cannot reform again.
