Which policy should be used to meet this requirement?

Explanations:

The Simple routing policy routes traffic to a single resource, and does not support returning multiple healthy EC2 instance IP addresses.

The Latency routing policy directs traffic to the region with the lowest latency, but it also does not return multiple healthy IP addresses for instances.

The Multi-value routing policy allows for multiple healthy IP addresses to be returned in response to DNS queries, which meets the requirement for the company.

The Geolocation routing policy routes traffic based on the geographic location of the user, but it does not facilitate the return of multiple healthy EC2 instance IP addresses.
