In a p-n junction diode not connected to any circuit

Question

In a p-n junction diode not connected to any circuit (A) the potential is the same everywhere (B) the p-type side is at a higher potential than the n-type side (C) there is an electric field at the junction directed from the n-side to the p-side (D) there is an electric field at the junction directed from the p-type side to the n-type side

At the junction, a potential barrier/depletion layer is formed, with n-side at higher potential and p-side at lower potential. Therefore, there is an electric field at the junction directed from the n-side to the p-side.

Q. In a p-n junction diode not connected to any circuit

the potential is the same everywhere

the p-type side is at a higher potential than the n-type side

there is an electric field at the junction directed from the n-side to the p-side

there is an electric field at the junction directed from the p-type side to the n-type side
