E=-∇V

The Attempt at a Solution



I think that the answer is C because it goes in the direction opposite the electric field and crosses through the most equipotential surfaces. Any confirmation or denial would be great.
Thank you.

Just in case it is hard to look at, I rotated the attachment to make it easier.
