Why each option

The command `docker node Is` is incorrectly capitalized; the correct command to list nodes in a Docker Swarm is `docker node ls` (lowercase 'ls').

AYes

The command contains a typographical error ('Is' instead of 'ls'), which prevents it from being a valid Docker CLI command to list nodes.

BNoCorrect

The command `docker node Is` uses a capital 'I' instead of the lowercase 'l' for 'ls', making it a syntactically incorrect and unrecognized command for listing nodes in a Docker Swarm cluster.
