Correct Answer
It sets a default permission mask that determines which permission bits are removed (masked out) from newly created files and directories
Explanation
The umask value is subtracted from the default permissions (666 for files, 777 for directories) to determine the actual permissions of newly created files/directories — a common umask of 022 results in files created with 644 and directories with 755.
