If a p-n junction diode is not connected to any circuit, then
A. the potential is same everywhere.
B. potential is not same and n-type side has lower potential than p-type side.
C. there is an electric field at junction direction from p-type side to n-type side.
D. there is an electric field at the junction directed from n-type side to p-type side.
