Which statement best describes the importance of time zones and stratum in NTP and their role in time synchronization across networks?

what is the answer?

$1.$Stratum represents the accuracy and reliability of a time server in the NTP hierarchy.

$2.$Time zones ensure that all devices within a network are synchronized to the same local time.

$3.$Time zones and stratum are used to determine the latency between time servers and synchronize clocks accordingly.

$4.$Time zones and stratum are not relevant in NTP; they solely rely on the system clock of each device.
