Answer: A

Explanation:

https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/snmp/configuration/15-e/snmp-15-e-book.pdf

There are three SNMP security levels (for SNMP v 1, SNMPv2c, and SNMP v 3):

+ noAuthNoPriv: Security level that does not provide authentication or encryption.

+ authNoPriv: Security level that provides authentication but does not provide encryption.

+ authPriv: Security level that provides both authentication and encryption.

For SNMPv3, "noAuthNoPriv" level uses a username match for authentication.
