Option 2: Startup items in /System/Library/StartupItems or /Library/StatupItems
Option 3: Uses .hidden to maintain a list of hidden files
Option 4: All of the Above

Answer 1

All statements about Mac OS are true: it's based on the BSD Darwin engine, uses specific directories for startup items, and maintains a list of hidden files via the .hidden file.

Step-by-step explanation:

Option 4: All of the Above is the correct answer. Mac OS is indeed based on the BSD Darwin engine which is the underlying foundation that provides the core operating system components in Mac OS. Additionally, it is true that startup items can be located in the directories /System/Library/StartupItems and /Library/StartupItems. These folders were used in earlier versions of Mac OS X to contain scripts and other items to be run automatically when the system starts. Furthermore, Mac OS has used a file named .hidden to specify which files should be hidden in the Finder. The .hidden file contains a list of filenames that the system treats as hidden.
