Which folder contains resources unique to each user in a macOS environment?

The correct choice identifies the /Library folder, specifically the user-specific resources found within the subfolder /Users/[username]/Library. This folder is critical in a macOS environment because it stores individual user preferences, application support files, and cached data relevant only to that user. It is designed to keep user settings and data isolated and allows for personalization of the environment without affecting other users on the same system.

In macOS, the top-level /Library folder contains resources that are available system-wide and can be shared among multiple users, such as application support files, fonts, and preferences that affect all users. The /System/Library folder is reserved for the core operating system components and should not be modified by users, as it contains necessary files for macOS to function correctly. The Root Library and Network Library do not pertain specifically to individual user resources, as the former is a more general category of system libraries and the latter is focused on network-related files shared across systems.

Thus, the /Users/[username]/Library is indeed the right answer as it caters to each user’s needs uniquely, providing an organized space for their specific data and preferences.
