easy

Consider the points lying on a straight line joining two fixed opposite charges. Between the charges there is

No point where electric field is zero

Only one point where potential is zero

All the charges are in unstable equilibrium

Both $(a)$ and $(b)$

Solution

(d) When two opposite charge separated by a certain distance then at two points potential is zero. One point exist between the charges and other exists outside them. Also no point, exists between the opposite charges. Where electric field is zero.
