Solution

The correct options are
B $$E_A > E_B$$
D $$V_A < V_B$$
Denser field lines give more electric field. At point B field lines are far away from each other compare to the point A. 
So $$E_A >E_B$$
and using $$E=-\frac{dV}{dr} $$ we can say that $$V_A<V_B$$
so, $$(A),(D)$$ are correct option.
