The correct answer is: (b) B and C

Work Step by Step

Lines of equal potential cross electric field lines at $90^{\circ}$ angles. If we connect point B and point C with a straight line, the line will cross the electric field lines at approximately $90^{\circ}$ angles. This is not true if we connect any other pair of points labeled in the diagram. The correct answer is: (b) B and C
