Answer is D.
It is not possible to make a script executable.

Because the default file permission is calculated by subtracting the umask from the base permission set. And Base permission for file is 666 and for directory is 777.

So the maximum permission you can give is by umask 000 which will give the newly created file 666,i.e read/write permission for the owner, group, and other (rw-rw-rw-)
