Correct option is B)

The electric potential is a scalar quantity. So the potential at the center is the sum of potential due to  number of charges. i.e,

The electric filed is a vector quantity. So the electric field cancel each other for the charges of opposite corner of polygon. Only charge will contribute the electric field at the center of polygon. thus,
