Best answer
Correct choice is (d) -z

Easiest explanation: uname command is used for printing the information about the current system.  -a is used for printing all the information including version name, kernel name, kernel release, machine hardware name etc. -s is used for printing only the kernel name while -v is used for printing the kernel version.
