Unix - Engineering

Q1:

The second set of the three permissions (r-) indicates that

A group has read permission only

B other has read permission only

C owner has read permission only

D group has write permission only

E None of the above

ANS:A - group has read permission only

First set in the sense owner and 2nd is group and 3rd is other. So mentioned that (r-) so obviously group has only read permission.
