C Correct answer
Explanation

Schottky diodes have a metal-semiconductor junction, unlike regular p-n junction diodes. This gives them faster switching speeds and lower forward voltage drop. Zener, Tunnel, and LEDs all use p-n semiconductor junctions. The metal-semiconductor junction is key to Schottky diode operation.
