Which permission setting corresponds to granting read, write, and execute only to the owner and no permissions to others?

• A. Owner has read, write, and execute; others have no permissions.
• B. Owner has read only; others have read.
• C. Everyone has read, write, and execute.
• D. Owner has execute only; others have no permissions.

Answer: (A)

Understanding Unix-like file permissions and how read, write, and execute are assigned to the owner, group, and others. The correct setting is when the owner has read, write, and execute, and others have no permissions. This means the owner can read the file, modify it, and run it if it’s a program, while no one else can access it at all. In common notation, that’s rwx for the owner and --- for everyone else, often represented numerically as 700. The other descriptions either grant some permission to others, or restrict the owner’s access, so they don’t meet the requirement of exclusive owner access with no permissions for others.
