 The app builder should use the Path component to meet the requirement of tracking different fields at each stage of the Opportunity sales process. The Path component is a Lightning component that displays the key fields and guidance for each stage of a standard or custom picklist field, such as the Opportunity Stage field. The app builder can configure the Path component to show the fields that need to be filled out and provide recommendations and sales strategies for each stage3. Option A, B, and C are not configuration steps that can meet this requirement.
