How should an app builder implement this requirement?

Universal Containers has a custom picklist called Support Level on the Account object. They would like to show the real-time value of Support Level on all case records.

How should an app builder implement this requirement?
A . Create a formula field on the Case object using the TEXT function.
B . Create a formula field on the Account object using the ISPICKVAL function.
C . Create a Process Builder and use a field update on the Case object.
D . Create a roll-up summary field using Support Level on the Account object.

Answer: A

Explanation:

Create a formula field on the Case object using the TEXT function. This is correct because a formula field can reference a field from a related object using dot notation, and the TEXT function can convert a picklist value to text. This way, the case record will always show the current value of the Support Level field on the account record.
