D Correct answer
Explanation

In database triggers (Oracle/PLSQL), trigger timing (BEFORE/AFTER/INSTEAD OF) is a mandatory clause. Every trigger must specify when it fires relative to the DML event. Options A, B, and C are incorrect - triggers can be implicit/automatic, they occupy space in database, and DML/DDL triggers both exist.
