The name 10BASE2 is derived from several characteristics of the physical medium.
The 10 comes from the maximum transmission speed of 10 Mbit/s (millions of bits per second).
The BASE stands for base band signalling
2 supposedly refers to the maximum segment length of 200 meters, though in practical use it can only run up to 185 meters. (The IEEE rounded 185 up to 200 to come up with the name 10BASE2, for consistency with the general standard).
10BASE2 coax cables have a maximum length of 185 meters (607 ft). The maximum practical number of nodes that can be connected to a 10BASE2 segment is limited to 30.
Option A Does not make sense here
Option B correct answer
Option C not correct answer because segment limited to 30
Option D it is also incorrect because not 50 feet (650 feet in 10BASE2 )
