Which property describes thermoplastics?

• A. Brittle and non-recyclable
• B. Remouldable, recyclable, High-impact resistant, tough
• C. Conductive
• D. Transparent but biodegradable

Answer: (B)

Thermoplastics are plastics that soften when heated and can be reshaped, melted, and reformed multiple times. That remoulding ability, together with their typically recyclability, is a defining feature. They can also be made tough and, with the right polymer and additives, offer good impact resistance. So describing them as remouldable, recyclable, high-impact resistant, and tough fits what thermoplastics are like in practice.

Some statements don’t fit as well: many plastics aren’t simply conductive, and while some thermoplastics can be transparent, biodegradability isn’t a general property of thermoplastics. Brittle and non-recyclable would describe materials that aren’t thermoplastics (or are specific poorly recycled types), and “transparent but biodegradable” mixes expectations that aren’t typical for the class as a rule.
