Explanation:

Question 11

In a medical context, a patient presenting with pain would go to the Emergency Department (ED) for care. The other options (Educational deficiency, Erectile dysfunction, Every day, Examining doctor) don't fit the context of a patient's medical visit for pain.

The human spinal column has 7 cervical vertebrae, 12 thoracic vertebrae, and 5 lumbar vertebrae. This is a standard anatomical fact. Option C matches this.

A herniated disc (like L4 - L5 herniated disc) means the disc is protruding (and often also compressed, but the key term "herniated" refers to the protrusion of the disc material). Among the options, "Protruding" (option B) is the most accurate description of the term's meaning in this context.

Answer:

C. Emergency department
