Answer Description

The MX (Mail Exchange) record is used in DNS to specify the mail servers responsible for receiving email messages on behalf of a domain. This record is essential for directing email traffic correctly to the organization's mail servers. The A record links a domain to an IP address for general queries but is not specific for mail servers. The CNAME record creates an alias for another domain name, not specifically used for mail servers. Lastly, the TXT record is used for providing arbitrary text about a host, commonly for security data like SPF or DKIM, not for mail server specification.
