A Correct answer
Explanation

Both thermosetting plastics and thermoplastics have almost the same tensile strength and durability. Both thermosetting and thermoplastics are non-biodegradable but thermoplastics can be recycled but thermo setting plastics cannot. The main difference between the two is that thermosetting plastics once set cannot be moulded again, but thermoplastic can be remoulded on heating.
