According to the distribution of electric field lines, the electric field lines at A are denser than those at B, so the field strength at A is greater than that at B, that is, EA > EB.

The equipotential line drawn outside point B intersects the electric field line at point A at point C,

Then the potential of point A is higher than that of point C, so the potential of point A is higher than that of point B, that is, φ A > φ B. Therefore, option D is correct.

So choose: D.
