The Fields component is a Lightning component that allows administrators to display fields from a record on a Lightning page based on certain conditions or criteria. For example, administrators can use filter logic to show or hide fields based on field values or user profiles. In this case, the administrator can use the Fields component to display fields that only apply to condos based on the value of a field that indicates the type of property.

An object-specific quick action is a type of action that allows users to do something in the context of a specific object, such as creating or updating a record, logging a call, sending an email, or launching a custom action. In this case, the administrator can create an object-specific quick action on the opportunity object that pre-populates certain fields with predefined values and allows users to quickly close an opportunity from the Salesforce mobile app. Reference: https://help.salesforce.com/s/articleView?id=sf.actions_overview.htm&type=5 https://help.salesforce.com/s/articleView?id=sf.actions_objectspecific_actions.htm&type=5
