D is not the correct answer here. The correct answer should be C - In the public DNS zone of contoso.com, add a CNAME record. Rationale: A custom domain can be applied to a WebApp without adding the domain to active directory. A canonical name (CNAME) resource record can be used, or an IPv4 host resource record (A) in conjunction with a text (TXT) record to verify ownership of the domain, and the WebApp will serve requests using the custom domain presented in the Hostname HTTP header accordingly.

the answer is C. the question pertains to webapp2 and not the need to add a domain in. thus we would be adding in a CNAME record.
