Final answer:
An office manager can access a protected document when a closing date with a password is set only by using the password; otherwise, they cannot access the document.
Step-by-step explanation:
If a closing date with a password is set, it implies that the document is protected and cannot be accessed freely. Access to such a document is strictly controlled through the use of the password.
Therefore, the correct answer to the question of whether a client's office manager can access the document is: A) Yes, with the password. Without the password, the document remains secure and inaccessible to unauthorized users, which includes the office manager unless they have been provided with the password.
