They are connected in parallel.

They are connected in series.

All diodes are connected in series with load so; in branch the current is same. ANS (A).

All diodes are connected in series and in + forward bias diode is on and in - reverse bias diode is on. So in all cases the diode is in farword bias and it will open so it will equal to the load current.

If we use 1, 2, 3, 4 diodes, when +ve cycle of ac is appeared across diode 1, then it will conduct and diode 2 will block full ac current then how will the diode 3 will get +ve cycle to conduct because full ac current is blocked by diode 2 which is connected in between diode 3 and diode 1 ?

As diodes are in series current flowing through them will equal to load current.

First 2 diodes area connected in series and another 2 are also. But these 2 groups are connected in parallel. And the values of these diodes are selected such that the circuit should be balanced. Therefore load current is equal.

Those are connected in series thats why the same resistance available in all diodes.

When d1 and d3 forward bias, this time full current flow between this diode and reverse bias this time full current flow between d2 and d4.
