A Correct answer
Explanation

Zener diodes are specifically designed for voltage regulation due to their sharp breakdown characteristic at a precisely controlled voltage. In reverse breakdown, they maintain nearly constant voltage across varying current. Schottky diodes are for fast switching. Tunnel diodes are for oscillators. LEDs emit light.
