A monitoring system exports host data in JSON format. An engineer wants to use this JSON as an Ansible inventory. The JSON structure is: {"all": {"hosts": ["router1", "router2"], "vars": {"ansible_user": "admin"}}}. Which statement is true?

This is a valid inventory structure and Ansible will parse it correctly.

This is invalid because the 'vars' key must be a list, not a dictionary.

This is invalid because the top-level key must be a group name other than 'all'.

This is invalid because the 'hosts' key must be a dictionary, not a list.
