A. `D_(1)` is forward biased and `D_(2)` is reverse biased and hence current flows from `A` to `B`
B. `D_(2)` is forward biased and `D_(1)` is reverse biased and hence no current flows from `B` to `A` and vice versa
C. `D_(1)` and `D_(2)` are both forward biased and hence current flows form `A` to `B`
D. `D_(1)` and `D_(2)` are both revrese biased and hence no current flows from `A` and `B` and vica-versa.

  1. Correct Answer – B
    In the given circuit p-side of `p-n` function `D_(1)` is connected to lower voltage and n-side of `D_(1)` to higher voltage. Thus `D` is reverse biased. The p-side of `p-n` junction `D_(2)` is lower potential.
    Therefore `D_(2)` is forward biased.
    Hence, current flows through the junction `B` to `A`.

  1. Correct Answer – B
    Diode `D_1` is reverse biased as p side is connected to negative potential and n side to ground.
    Diode `D_2` is forward biased as p side is grounded and n side is at negative potential.
