(A, B, D) diode is reverse biased when the potential at its cathode $(V_K)$ is higher than the potential at its anode $(V_A)$,i.e.,$V_K > V_A$.Let us analyze each option:$A$: $V_A = +5V$,$V_K = +10V$. Since $V_K > V_A$,it is reverse biased.$B$: $V_A = -12V$,$V_K = -10V$. Since $V_K > V_A$,it is reverse biased.$C$: $V_A = 0V$,$V_K = -10V$. Since $V_A > V_K$,it is forward biased.$D$: $V_A = 0V$,$V_K = +5V$. Since $V_K > V_A$,it is reverse biased.Note: In many standard textbook problems of this type,multiple options might satisfy the condition. Based on the provided image options,$A$,$B$,and $D$ are all reverse biased. However,if we assume the question asks for a specific configuration or if there is a single correct choice intended,we evaluate the potential differences. Given the standard interpretation,$A$,$B$,and $D$ are all reverse biased.
