Which file system can be used to prevent scripts from being executed in certain directories?

The ability to prevent scripts from being executed in certain directories is facilitated by the use of the "noexec" option in mount options. Specifically, when a file system is mounted with the noexec option, it disallows the execution of any binaries or scripts located on that file system. This is particularly useful for directories that are accessible by users but should not contain executable files for security or stability reasons.

When a file system is mounted with this option, any attempt to execute a script or binary file will result in an error, helping to mitigate potential risks associated with unauthorized or harmful script execution. This feature is commonly used on partition types where execution of applications is not necessary or desirable, such as temporary file systems or locations where only data file storage is required.

Other file systems like ext4, tmpfs, and nfs are types of file systems but don't inherently provide the functionality to restrict execution without being configured with specific mount options, such as noexec. Thus, the noexec option stands out as the correct choice for controlling script execution in specified directories.
