What term describes forcefully blinking the eyes using all the muscles in the face, including those in the forehead?

• A. Forcefully blinking the eyes using all the muscles in the face, including those in the forehead
• B. Rapid blinking due to fatigue
• C. An involuntary spasm of the eyelids
• D. A type of vision loss

Answer: (A)

The action being tested is a precise description of what happens when someone forces a full-face blink, engaging all facial muscles including the forehead. The best choice directly states that exact behavior—forcefully blinking the eyes using every facial muscle, even the forehead—so it matches the described act without adding or implying other conditions.

The other options describe different phenomena: rapid blinking from fatigue refers to speed and is not about full facial engagement; an involuntary spasm of the eyelids points to a specific motor disorder (blepharospasm) rather than a deliberate, broad facial contraction; and vision loss is unrelated to the mechanics of blinking.
