Options

• Option A

  the potential in the same everywhere.

• Option B

  the P-type side is at a higher potential then the N-type side.

• Option C

  there is an electric field at the junction directed from the N-type side to the P-type side.

• Option D

  there is an electric field at the junction directed from the P-type side to the N-type side.
