Choose the correct answer from the following options:

Only diode A is in forward biasing. Just two diodes A and B are in forward biasing. All diodes A, B and C are in forward biasing. None of the diodes A, B and C are in forward biasing.

All diodes A, B and C are in forward biasing.

$\text{All three diodes are forward biased}$ $ \text{Potential of left part is higher compared to right part}$
