Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Permission 764 in octal means: Owner (7) = read(4)+write(2)+execute(1), Group (6) = read(4)+write(2), Others (4) = read(4). So everyone can read, owner has full access, and group can read/write. Option C correctly states: everyone can read, group including owner can write, owner alone can execute.
