RETURN NUMBER 
IS 
  user_count NUMBER;
BEGIN
  SELECT COUNT(*) INTO user_count FROM users;
  RETURN user_count;
END;
/

Select the statements that are correct.

(Select all acceptable answers.)

When the users table is dropped any function, procedure, or package using count_users is invalidated.

When the users table is dropped, any function, procedure, and package using count_users, inside dynamic SQL is invalidated.
