What is an example of a polymorphic lookup field in Salesforce?
Correct Answer: D
A polymorphic lookup field is a relationship field that can reference one of several different types of objects.
For example, the Who relationship field of a Task can be a Contact or a Lead. The WhatId field on the standard Event object is another example of a polymorphic lookup field, as it can reference any object that allows activities, such as Account, Opportunity, Case, etc. To determine the type of the referenced object, you can use the What.Type field in a SOQL query. You can also use the TYPEOF clause to filter or select fields based on the object type. References:
