The DNS record that points to a domain's mail server is:

• A. A
• B. NS
• C. MX
• D. SRV

Answer: (C)

The purpose of this DNS record is to tell the world where to deliver email for the domain. That role belongs to the mail exchanger (MX) record. It specifies one or more hostnames that act as the mail servers for the domain, often with a priority so mail can be retried if the primary exchanger isn’t reachable. The hostname in an MX record is resolved to an IP via A or AAAA records, but the critical piece for mail routing is that MX type designates the mail servers. Other DNS record types don’t define where mail goes: A records map a domain to an IP address, NS records list the authoritative name servers, and SRV records provide service endpoints (like for specific protocols) rather than mail routing.
