Correct Answer: C

Rationale: Clozapine's most serious adverse effect is agranulocytosis (choice C), a severe neutropenia risking infection, requiring monitoring. Bronchoconstriction (choice A), seizures (choice B), and tardive dyskinesia (choice D) occur but are less life-threatening. Agranulocytosis defines clozapine's risk profile.
