access privileges or privileges

Explanation:

The employees at Manuel's company have different _access privileges _ , based on the situation described.

The permissions to be able to perform some actions on some files are called privileges.  So, some employees have limited privileges (only able to open files, but not to edit them), and other have extended privileges (allowing them to open and edit files).  

Although possible, it's unlikely that the employees have different different antivirus software, broadband connections or firewalls.  And no indication in the situation described lead to think that.

It's unclear in your question if "access privileges" is one or two answer choices.  Usually, we talk about "access privileges" but it would also be just "privileges".   If these are two choices, go for "privileges", since all employees have access to the files, so they don't have different access.
