. $\square$ A. A bus topology uses terminators on any loose end of the bus. The terminator is designed to absorb the signal so that it does not bounce back on the wire and collide with other data. ख B is incorrect because a star topology does not use terminators; it uses a central hub or switch that connects systems to the network. C is incorrect because a mesh topology has each system connecting to each other system. D is incorrect because a ring topology has no beginning and no end, so there are no "loose ends" to put a terminator on. E is incorrect because a wireless network does not use cables at all.
