The correct answer is A. stratum.
NTP (Network Time Protocol) is a protocol used to synchronize the clocks of computers to a common reference time source. NTP operates in a hierarchical manner, with a network of time servers that provide time synchronization to clients.
The NTP hierarchy is organized into strata, with stratum 0 being the highest and most accurate level. Stratum 0 time sources are typically atomic clocks or GPS receivers that are directly connected to the network. These time sources are considered to be the most accurate and reliable sources of time.
Stratum 1 servers are directly connected to stratum 0 servers and act as time servers for other devices on the network. Stratum 2 servers are connected to stratum 1 servers, and so on. Each stratum represents a level of time source hierarchy, with the highest stratum being the most accurate and reliable.
The stratum value indicates the number of hops from the authoritative time source. For example, a server that is directly connected to a stratum 1 server would be at stratum 2. A server that is connected to a stratum 2 server would be at stratum 3, and so on.
Therefore, the value that indicates the distance from the NTP authoritative time source is the stratum.
