Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
UI policy with 'Choice' action set to 'Set choices' conditionally.
A UI policy can conditionally set the choices of a choice field on the client side using the 'Choice' action with 'Set choices' conditionally. This allows dynamic filtering of choice values based on other field values on the same record. Option A (data policy) is server-side and cannot dynamically change client-side choices. Option C (reference qualifier) applies only to reference fields, not choice fields. Option D (client script) can hide or show options but is not the standard declarative approach; UI policy is preferred for this requirement.
