D Correct answer
Explanation

A umask of 027 (octal) means removing write permissions for group (2) and all permissions for others (7). Starting from default file permissions 666 (rw-rw-rw-), subtracting 027 gives 640 (rw-r-----): read/write for owner, read-only for group, no permissions for others. The key is understanding that umask subtracts from the default 666 for files.
