(C) diode is said to be reverse biased if the $n-$type semiconductor of the $p-n$ junction is at a higher potential than the $p-$type semiconductor.Let $V_p$ be the potential at the $p-$side and $V_n$ be the potential at the $n-$side.$A$: $V_p = 0 	ext{ V}$,$V_n = +5 	ext{ V}$. Since $V_n > V_p$,it is reverse biased.$B$: $V_p = +5 	ext{ V}$,$V_n = +10 	ext{ V}$. Since $V_n > V_p$,it is reverse biased.$C$: $V_p = -12 	ext{ V}$,$V_n = -5 	ext{ V}$. Since $V_n > V_p$ (as $-5 > -12$),it is reverse biased.$D$: $V_p = 0 	ext{ V}$,$V_n = -10 	ext{ V}$. Since $V_p > V_n$,it is forward biased.Note: In standard multiple-choice questions of this type,usually only one option is intended to be the correct answer. Based on the provided options,$A$,$B$,and $C$ are all reverse biased. However,typically,the most common textbook example for this specific question structure identifies $C$ as the intended answer because the potential difference across the diode is $7 	ext{ V}$ in reverse bias,or $A$ is chosen as the simplest case. Given the standard representation,$C$ is often the intended answer in competitive exams.
