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

• A 2023 investigation examined the facial expressions of wolves and domestic dogs.
• In the investigation, facial expressions were coded using 46 distinct facial actions.
• The “ears rotator” facial action is seen in wolves.
• Dog breeds with upright (wolf-like) ears can produce the “ears rotator” facial action.
• Dog breeds with drooped or partly drooped (non-wolf-like) ears cannot produce the “ears rotator” facial action.

The student wants to contrast dog breeds with wolf-like ears and dog breeds with non-wolf-like ears. Which choice most effectively uses relevant information from the notes to accomplish this goal?

A

In a 2023 investigation, dog breeds with non-wolf-like ears were able to produce the same facial movements that wolves could.

B

Non-wolf-like ears are drooped or partly drooped, but wolf-like ears are different: they are upright and can produce the “ears rotator” facial action.

C

Like wolves, dog breeds with upright ears can produce the “ears rotator” facial action, while those with drooped or partly drooped ears cannot.

D

One difference between dog breeds with wolf-like ears and dog breeds without them is that wolf-like breeds cannot produce the “ears rotator” facial action.
