(A) $PN$ junction diode is forward biased when the potential at the $P$-side $(V_P)$ is greater than the potential at the $N$-side $(V_N)$,i.e.,$V_P > V_N$.For option $(A)$: $V_P = 0 	ext{ V}$,$V_N = -3 	ext{ V}$. Since $0 > -3$,$V_P > V_N$. This is forward biased.For option $(B)$: $V_P = -4 	ext{ V}$,$V_N = -2 	ext{ V}$. Since $-4 For option $(C)$: $V_P = 2 	ext{ V}$,$V_N = 5 	ext{ V}$. Since $2 For option $(D)$: $V_P = -2 	ext{ V}$,$V_N = 2 	ext{ V}$. Since $-2 Therefore,option $(A)$ is the correct answer.
