C Correct answer
Explanation

Triggers are fired by DML operations (INSERT, UPDATE, DELETE). Among the options, only Delete is a DML operation that can cause a trigger to fire. Drop and Alter are DDL operations and don't fire triggers. Rollback is a transaction control command, not a DML operation.
