In the code snippets below, which regex pattern used by the re Python module will create a list of matches for starts with 'GigabitEthernet' and has a digit $1-9$ at the end, immediately followed by a space?

interface$\_$pattern $=$ r$\text{'}($GigabitEthernet$[1-9])\text{'}$

interface$\_$pattern $=$ r$\text{'}($GigabitEthernet$[1|9])\backslash$s$\text{'}$

interface$\_$pattern $=$ r$\text{'}($GigabitEthernet$[1-9])\backslash$r$\text{'}$

interface$\_$pattern $=$ r$\text{'}($GigabitEthernet$[1-9])\backslash$s$\text{'}$

interface$\_$pattern $=$ r$\text{'}($GigabitEthernet$(1-9))\backslash$s$\text{'}$
