Answer - C.

The AWS documentation mentions the following.

By default, each hosted zone that you create gets a different set of four name servers-a different delegation set.

If you create a lot of hosted zones, maintaining different delegation sets can be difficult and time consuming.

Amazon Route 53 lets you create a delegation set that you can reuse with multiple hosted zones.

To ensure that the same set of nameservers are used across multiple domains in Route53, you would need to create a delegation set. The delegation set is a set of four Amazon Route 53 authoritative name servers that Route53 automatically assigns when you create a delegation set. The name servers are grouped together in a set so that you can use them with multiple hosted zones.

To create a delegation set via the console, follow these steps:

  1. Open the Route53 console.
  2. In the navigation pane, choose "Delegation Sets."
  3. Choose "Create a delegation set."
  4. Enter a name for the delegation set.
  5. Choose "Create."
  6. Note down the delegation set ID that is displayed in the console after you create the delegation set.

To use the delegation set for a hosted zone, follow these steps:

  1. Open the Route53 console.
  2. In the navigation pane, choose "Hosted Zones."
  3. Choose the name of the hosted zone that you want to use the delegation set with.
  4. Choose "Create Record Set."
  5. In the "Name" field, enter the domain name that you want to use the delegation set with.
  6. Choose "NS" for the type of record set.
  7. In the "Value" field, enter the delegation set ID.
  8. Choose "Create."

Repeat the above steps for each domain that you want to use the same set of nameservers with.

Note that you can also create a delegation set via the AWS CLI by using the create-delegation-set command. Additionally, creating a dual hosted zone in Route53 would not achieve the goal of using the same set of nameservers across multiple domains. Creating a primary hosted zone in Route53 would create a new set of name servers for that hosted zone, and would not allow you to use the same set of name servers for other hosted zones.
