A company hosts 5 web servers in AWS. They want to ensure that multiple values for a DNS query should be returned and traffic routed to multiple IP addresses. In addition, you want to associate your routing records with a Route 53 health check. Which routing policy should be used to fulfill this requirement?

Answer options:

A.Simple
B.Weighted
C.Multivalue Answer 
D.Latency

Correct Answer - C
The AWS Documentation mentions the following to support this:
If you want to route traffic randomly to multiple resources such as web servers, you can create one multivalue answer record for each resource and, optionally, associate an Amazon Route 53 health check with each record.
For example, suppose you manage an HTTP web service with a dozen web servers where each has its own IP address. No web server could handle all the traffic. But if you create a dozen multivalue answer records, Amazon Route 53 responds to DNS queries with up to eight healthy records in response to each DNS query. Amazon Route53 gives different answers to different DNS resolvers. If a web server becomes unavailable after a resolver cache a response, client software can try another IP address in the response.
Simple routing policy – Use a single resource that performs a given function for your domain, such as a web server that serves the example.com website.
Latency routing policy – Use when you have resources in multiple locations, and you want to route traffic to the resource that provides the best latency.
Weighted routing policy – Use to route traffic to multiple resources in proportions that you specify.
Multivalue answer routing policy – Use when you want Route53 to respond to DNS queries with up to eight healthy records selected randomly.
