Answer: A

Explanation:

For a NAT gateway in Azure, you need to use a Standard SKU public IP address with a static allocation method. Basic SKU public IP addresses and dynamically assigned IP addresses are not supported with NAT gateways.

Based on the table provided:

IP3 is IPv4, uses Standard SKU, and is static.

IP5 is IPv6, uses Standard SKU, and is static.

Therefore, the public IP addresses that can be used as the public IP address for NAT1 are:

A. IP3 and IP5 only

This is because both IP3 and IP5 meet the requirements for use with a NAT gateway, which requires Standard SKU and static IP allocation.
