Correct Answer: B,D
The provided PHP code attempts to insert a new row into the 'users' table with the primary key value '1', which already exists in the table. Since 'id' is a primary key, this action will result in a primary key violation. Upon encountering this violation, the PDOException will be caught by the catch block, where it will echo 'Failure!' and subsequently throw the exception. Hence, the user will see the 'Failure!' message.
