The Service Manager provided the app builder with color code requirements for case age on...

The correct answer is C. Formula Field.

The Service Manager wants a visual color indicator based on the age of an open Case: green for new, yellow for one day old, and red for three days old. This can be implemented with a formula field using conditional logic and the Salesforce IMAGE() function to display different colored indicators based on Case age. Salesforce documentation confirms that the IMAGE function is available in formula fields and can display an image based on field values.

A formula field can evaluate the case age using fields such as CreatedDate , TODAY() , and IsClosed , then return the correct colored image.

A. Custom Button is incorrect because this is not a user action.

B. Quick Action is incorrect because the requirement is display-based, not action-based.

D. Lightning Web Component could do this with code, but a formula field is the simplest declarative Platform App Builder solution.
