The correct answer is: C. Open explicit
To set a password for a database in Microsoft Access, you need to open the database in exclusive mode. This means that you will be the only person who can access the database until you close it. Once you have opened the database in exclusive mode, you can set a password by clicking on the File tab, then clicking on Info, and then clicking on Protect Database. In the Protect Database window, click on the Password tab, and then type in a password in the Password and Confirm Password boxes. Click on the OK button to save your changes.
The other options are incorrect because they do not allow you to set a password for the database.
- Open read only allows you to open the database but you cannot make any changes to it.
- Open write only allows you to open the database and make changes to it, but other people cannot open the database while you are using it.
- Open exclusive allows you to open the database and make changes to it, and no one else can open the database until you close it.
