p-n junction diode, rectifiers, Zener diode

Why this is asked: A Zener diode is the one diode deliberately operated in reverse breakdown, using its near-constant voltage there for regulation — every ordinary diode is designed to avoid that same region. A full-wave rectifier conducts on both halves of the input cycle; a half-wave rectifier, only one.

•Consider the following statements A and B and identify the correct answer (refer to the given $I$ – $V$ graph): A. For a solar cell, the $I$ – $V$ characteristic lies in the IV quadrant of the given graph. B. In a reverse-biased p-n junction diode, the current measured (in $μ$ A) is due to majority charge carriers.
