During a penetration testing engagement, you are required to perform credential testing against a secure shell (SSH) service known to be running on the target machine with the IP address 192.168.1.50. Based on the client's information, username enumeration is not a concern, and you have been provided a list of potential usernames and a common password to test. Which command should you use to perform this task efficiently using Hydra?
-L /path/to/userlist.txt -p password ssh://192.168.1.50
-C /path/to/creds.txt ssh://192.168.1.50
-U /path/to/userlist.txt -password password ssh://192.168.1.50
-l user -P /path/to/common-password.txt ssh://192.168.1.50
