Step 1: Break the stem into the three GCS axes and match each phrase to its numeric value rather than guessing the total.
Step 2: Eye opening: the patient opens the eyes only when a painful stimulus is applied, which scores 2 out of 4 (spontaneous = 4, to voice = 3, to pain = 2, none = 1). Verbal: "confused" equals disoriented conversation, scoring 4 out of 5 (oriented = 5, confused = 4). Motor: "localising pain" means the patient moves a hand toward the painful site, scoring 5 out of 6 (obeys = 6, localises = 5).
Step 3: Sum the parts:
\[E_2 + V_4 + M_5 = 11\]
A score of 11 places the patient in the moderate head injury range (GCS 9 to 12). Options 6, 12 and 7 would require different component scores and do not fit the description.
\[\boxed{11}\]
