The correct answer is D.

Universal Containers wants the Account Region value to appear on related Contact records and stay in sync whenever the Account value changes. A cross-object formula field on Contact is the best declarative solution because it dynamically references the parent Account field. Salesforce Trailhead explains that a cross-object formula can pull information from a parent object through a lookup relationship, such as showing Account information on Contact.

Because Account Region is a picklist, the formula must convert the picklist value to text using the TEXT() function. Trailhead gives the same pattern with Account Industry on Contact: TEXT(Account.Industry) .

B is incorrect because ISPICKVAL() checks whether a picklist equals a specific text value and returns true/false; it does not display the picklist value.

A and C are incorrect because creating a copied field and trying to update it through a relationship is unnecessary when a formula field can stay synchronized automatically.
