Answer:
The correct answer is option b. "pass through both ears".
Explanation:
In medicine, a frontal or coronal section through the human body will provide mirror right and left images dividing the body into front and back, also known as dorsal and ventral ( or belly and back). In order to obtain these images, the coronal section must pass through both ears, dividing each ear into half. I attached a image to illustrate the way the coronal plane is obtained.
