Correct answer: C — Partial pulpotomy (Cvek) with MTA and composite restoration

For a vital permanent tooth with a small pulp exposure due to trauma and a closed apex, a partial pulpotomy (Cvek pulpotomy) is the treatment of choice within the first 24 hours. MTA or calcium hydroxide is placed over the exposed vital pulp after removing 2 mm of superficial pulp tissue. This preserves pulp vitality, promotes continued root development (if apex is open), and has a success rate exceeding 90%. Direct pulp capping can also be considered for very small exposures.
