Selected Answer: A
TXT (Text) records are used for various purposes in DNS, and they are specifically used to implement email authentication mechanisms like SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail). These mechanisms help verify the source of incoming emails and ensure they are sent from trusted sources.
