In the figure assuming the diodes to be ideal

A

`D_1 and D_2 `are both forward biased and hence current flows from A to B

B

`D_1 and D_2` are both reverse biased and hence no current flows from A to B

C

`D_1 `is forward biased and D, is reverse biased and hence current flows from A to B

D

`D_2` is forward biased and D, is reverse biased and hence no current flows from B to A
