Explanation
NTP (Network Time Protocol) is the standard protocol used to synchronize clocks across network devices. Accurate time synchronization is critical for logging, security certificates, Kerberos authentication, and network protocols. FTP (option A) is used for file transfers. NNTP (option B) is the Network News Transfer Protocol used for Usenet newsgroup distribution. BGP (option C) is Border Gateway Protocol, used for routing between autonomous systems on the internet. NTP operates over UDP port 123 and uses a hierarchy of time sources called strata.
