[A]. chmod g+x note
[B]. chmod u+w note

Answer: Option C

Explanation:

Users selection:

u - user: the owner of the file.
g - group: users who are members of the file's group.
o - others: users who are not the owner of the file or members of the group.
a - all: all three of the above, is the same as ugo.
