You have a requirement to host both a private and public hosted zone for the same domain name in Route53. How can this be achieved?

Answer options:

A.This is not possible in Route53
B.Create different resources records in the same hosted zone
C.Configure split-view DNS in Route53
D.Create one hosted zone with both the private and public option

Answer - C
This is mentioned in the AWS documentation
You can use Amazon Route 53 to configure split-view DNS, also known as split-horizon DNS. If you want to maintain internal and external versions of the same website or application (for example, for testing changes before you make them public), you can configure public and private hosted zones to return different internal and external IP addresses for the same domain name. Just create a public hosted zone and a private hosted zone that have the same domain name, and create the same subdomains in both hosted zones
