Answer - B - A ring topology is a network topology or circuit arrangement in which each network device is attached along the same signal path to two other devices, forming a path in the shape of a ring.

Key Takeaway: Identifying a physical ring topology is easy. A ring topology connects to exactly two other nodes, forming a single continuous pathway for signals through each node. Ring topologies are not used these days, due to its apparent disadvantages which include high-impact on network performance if network changes are made and the fact that failure of a single node causes the entire network to fail.
