The correct answers are C. Lightning App Builder and D. Lightning components in Setup.

In Lightning App Builder, custom Lightning components that are configured for use in Lightning App Builder appear in the Lightning Components pane.

In Setup → Lightning Components, Salesforce allows admins to view a list of Lightning Web Components and Aura components in the org.

Why others are incorrect:

A. Visualforce components in Setup lists Visualforce custom components, not Lightning components.

B. Salesforce Optimizer App analyzes org configuration and recommendations; it is not the place to list available custom Lightning components.

A roll-up summary field requires a master-detail relationship. Since Galaxy__c and Star__c currently have a lookup relationship, the app builder cannot create a standard roll-up summary field to count related Star__c records. The lookup must be converted to master-detail first, with Galaxy__c as the master and Star__c as the detail. Salesforce Trailhead confirms that roll-up summary fields display values on the master record based on directly related detail records in a master-detail relationship.

The correct answer is C. Validation Rule.

DreamHouse Realty needs to prevent an Opportunity from entering the Qualified stage unless Expected_Close_Date__c is populated. A validation rule is the correct feature because validation rules check whether record data meets defined requirements before the record can be saved. Salesforce also provides examples of validation rules used to control Opportunity stage changes.

Example formula:

AND(

ISPICKVAL(StageName, " Qualified " ),

ISBLANK(Expected_Close_Date__c)

)

A is incorrect because record types do not enforce this conditional requirement by themselves.

B is incorrect because page layouts cannot reliably enforce conditional required fields by stage.

D is incorrect because Activity History does not validate data entry.
