Explanation:
The correct answer is A. To add a custom domain to webapp1, the first step is to create a DNS record. You can use either a CNAME record or an A record to map a custom DNS name to the Azure App Service. CNAME records are typically used for mapping custom DNS names, while A records are used for root domains. This setup allows the custom domain (www.contoso.com) to point to the web app.
