Correct Answer is A

Explanation

The Glasgow Coma Scale (GCS) measures three aspects: Eye response, verbal response, and motor response.

Eye response: Opens eyes to pain (score 2).

Verbal response: Uses inappropriate words (score 3). Motor response: Flexion withdrawal from pain (score 4). Total GCS = 2 (eyes) + 3 (verbal) + 4 (motor) = 9.
