While researching a topic, a student has taken the following notes:

• Generally, an object will heat up when twisted.
• The twisting of an object is known as torsion.
• A 2019 study led by Zunfeng Liu and Ray Baughman tested the torsional heating of various fibers.
• When a 0.7-millimeter-thick sample of single-ply nickel-titanium (NiTi) wire was twisted, its average surface temperature increased by $21.3^{\circ }\text{C}$.
• When a 2-millimeter-thick sample of ethylene propylene diene monomer (EPDM) rubber fiber was twisted, its average surface temperature increased by $12^{\circ }\text{C}$.

The student wants to contrast the two samples. Which choice most effectively uses relevant information from the notes to accomplish this goal?

A

In 2019, researchers studied the effect of torsional heating on various fibers, including samples of EPDM rubber and single-ply NiTi wire.

B

The EPDM rubber sample used in the 2019 study was thicker than the single-ply NiTi wire sample.

C

Twisting an object will generally cause its temperature to increase, a process known as torsional heating.

D

When the fibers were twisted as part of the 2019 study, the surface temperature of both samples increased.
