Kevin is creating a function to execute part of a user story deployment step.

Comprehensive and Detailed 100to 150 words of Explanation From Copado Extension builder topics:

Kevin should select CObjectField Expression because the requirement is to retrieve a specific field value from an object record or from a related parent record. Dynamic Expressions are used in Copado to resolve contextual values dynamically and pass those values into Functions or Salesforce Flow steps. A field-focused expression type is appropriate when the automation must pull a particular value rather than reference an entire record.SObject Expression relates more broadly to Salesforce object context, but the question specifically asks for a field in a record or parent record. User Expressions would apply to user-related context, not object field retrieval. Therefore, CObjectField Expression is the correct answer.
