Answer: D

Explanation:

The user has the wrong shell assigned to the account, which is causing the issue. The output 1 shows that the user’s shell is set to /bin/false, which is not a valid shell and will prevent the user from logging in. The output 2 shows that the user’s home directory has the correct permissions (drwxr-xr-x), and the output 3 shows that the user entered the correct password and was accepted by the SSH daemon, but the session was closed immediately due to the invalid shell. The other options are incorrect because they are not supported by the outputs.
