Which statement correctly describes the permissions represented by rw-r--r--?

• A. The owner has read and execute; the group has read; others have read.
• B. The owner has read and write; the group has read; others have read.
• C. The owner has read; the group has read and write; others have none.
• D. The owner has write only; the group has execute; others have execute.

Answer: (B)

File permissions are shown as three groups of characters: the owner, the group, and others. Each group has three positions that indicate read (r), write (w), and execute (x) permissions, or a dash (-) if that permission isn’t granted. In rw-r--r--, the owner’s group is rw-, meaning the owner can read and write but not execute. The group’s group is r--, so group members can read only. The others’ group is r--, so everyone else can read only. Since there’s no execute permission anywhere, the description that the owner has read and write, the group has read, and others have read matches exactly.
