At Which Point (Or Points) Is the Electric Field Zero

Multiple Choice

At which point (or points) is the electric field zero N/C for the two point charges shown on the x axis?

A) The electric field is never zero in the vicinity of these charges.
B) The electric field is zero somewhere on the x axis to the left of the +4q charge.
C) The electric field is zero somewhere on the x axis to the right of the -2q charge.
D) The electric field is zero somewhere on the x axis between the two charges, but this point is nearer to the -2q charge.
E) The electric field is zero at two points along the x axis; one such point is to the right of the -2q charge and the other is to the left of the +4q charge.
