Which material can be shaped a number of times?

Explanation:
Polymorph is a thermoplastic that softens when heated and can be reshaped, cooled to harden, and then reheated again for reshaping. Because it doesn’t chemically cure, it can be remolded many times without degrading. The other options don’t fit this repeated reshaping: composites are typically cured and set, not remelted; QTC is used for sensing/conductivity rather than reshaping; smart materials may respond to stimuli but aren’t generally chosen for repeated, easy reshaping by heating like Polymorph.
