B is very correct ✔️💥
An insulated charge will not produce current if it doesn't move because current means movement of charge✔️
Potential difference is workdone in moving a charge...No Potential difference since the charge doesn't move✔️
Therefore, B is correct 💥✔️

The correct option is C
An insulated charged body carrying positive charge have the following properties:
1. It contains excess protons or positive charge, it is electron deficient.
2. Charges have space round them where electric forces can be felt called electric field.
3. It possesses potential energy since it is a charge on an electric field.

Na lie. Since it is insulated, the charge is static and there is no electric current. Also, since myschool says that all answers are correct, how does it possess potential energy because its position is not stated in the question.
The correct answer is B. i and ii only.
Explanation:
i. It contains excess positive charges - This statement is true. An insulated charged body carrying positive charge contains excess positive charges, which are responsible for creating an electric field around the body.
ii. It creates an electric field - This statement is true. An insulated charged body carrying positive charge creates an electric field around it, which can exert forces on other charged particles in its vicinity.
iii. It possesses potential energy - This statement is not necessarily true. The potential energy of a charged body depends on its position relative to other charged bodies in the vicinity. If the body is isolated and not interacting with other charged bodies, then it does not possess potential energy.
iv. It carries electric current - This statement is not true. An insulated charged body carrying positive charge does not necessarily carry electric current. Electric current is the flow of charged particles through a conductor, and an insulated charged body is not a conductor.
1. It contains excess positive charges 
By definition, a positively charged body has more positive charges than negative charges, so this is true.
It creates an electric field
Any charged body, positive or negative, generates an electric field around it, so this is true.
It possesses potential energy
A charged body has electrostatic potential energy due to the work done in bringing charges together or in the field it creates. True.
It carries electric current 
A body does not carry electric current unless there is a complete conducting path. An isolated (insulated) body cannot have a continuous flow of charges, so this is false.
Correct answer:
C. i, ii, iii only
