The correct answer is C. in.
The head is made up of several parts, including the skull, the brain, the eyes, the ears, the nose, the mouth, and the throat. The pain can be felt in any of these parts, but the most common location is the forehead. The pain can also be felt in the temples, the back of the head, or the neck.
The pain can be caused by a variety of things, including a headache, a migraine, a sinus infection, a toothache, or a tension headache. If the pain is severe or if it is accompanied by other symptoms, such as fever, nausea, or vomiting, it is important to see a doctor.
