  2% (1)

  4% (2)
• C

• D
  92% (48)

Explanation

A switch provides the fewest collisions because each port on a switch creates its own individual collision domain, and switches operate in full-duplex mode, effectively eliminating collisions entirely on each segment. A hub is a single shared collision domain-all devices connected to a hub compete for the same medium, leading to the most collisions. A repeater simply amplifies and regenerates the signal but does not segment collision domains, so it does not reduce collisions. A bridge divides a network into two collision domains, reducing collisions compared to a hub, but a switch (essentially a multi-port bridge) divides the network into as many collision domains as it has ports, making it far superior.
