Field Sets on Standard and Custom Objects

A.

Field Sets work on both standard and custom objects in Salesforce.

A Field Set is a grouping of fields that can be displayed on a Visualforce page or in a Lightning component. It is a convenient way to group fields together for display or manipulation in code, without needing to hardcode the fields into the page or component.

Field Sets can be created on any object in Salesforce, whether it is a standard object (e.g. Account, Contact, Opportunity) or a custom object (e.g. Project, Campaign, Product). When creating a Field Set, you simply select the object you want to create it for and then choose the fields you want to include.

So, to answer the question, the correct answer is A. True, Field Sets work on both Standard as well as Custom Objects in Salesforce.
