A Correct answer
Explanation

The REPLACE keyword in CREATE OR REPLACE PROCEDURE performs two actions: if a procedure with the same name already exists, it drops the existing procedure first, then creates the new version. This allows you to update procedure definitions without manually dropping them first. Option A correctly describes this behavior. Option B is incorrect because REPLACE does replace with the new version, not leave it missing. Option C is incorrect because a change does occur - the old version is dropped. Option D is incorrect because REPLACE is a valid and commonly used option.
