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 1-millimeter-thick sample of dimethicone fiber was twisted, its average surface temperature increased by $1.8^{\circ }C$
• When a 4-millimeter thick sample of styrene-ethylene-butylene-styrene (SEBS) rubber fiber was twisted, its average surface temperature increased by $3.5^{\circ }C$

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

A

The SEBS rubber sample used in the 2019 study was thicker than the dimethicone sample.

B

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

C

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

D

In 2019, researchers studied the effect of torsional heating on various fibers, including samples of SEBS rubber and dimethicone.
