A

Longer polymer chains generally increase tensile strength due to entanglement.

B

Shorter polymer chains produce stronger materials because they allow for more flexibility.

C

The length of polymer chains has no effect on tensile strength.

D

Longer chains decrease tensile strength due to increased brittleness.

Understanding the Answer

Let's break down why this is correct

Longer chains create many twists and overlaps. Other options are incorrect because The idea that more flexibility gives more strength is a mix‑up; This thinks chain length has no effect.
