The query must contain the Application Service and Configuration Item nodes, the appropriate relationship between those nodes, and filters that restrict the results to the named Application Service and operational CIs.
Option A only adds Operational Status and Name as result columns. Displaying a field as a column does not filter records according to that field, so non-operational CIs could still appear.
Option C unnecessarily adds the Business Application class. The requirement is to find CIs belonging to a specific Application Service; no Business Application condition or relationship is required. Adding unnecessary classes can complicate the query and potentially alter its results.
CMDB Query Builder is designed to traverse relationships between CMDB classes. The guide similarly explains that Application Services and their related infrastructure should be represented through a CMDB query and connected through CMDB relationships.
Therefore, the correct sequence is Option B.
