Which among the curves shown in Figureb cannot possibly represent electrostatic field lines?

Solution
$(a)$ The field lines showed in $(a)$ do not represent electrostatic field lines because field lines must be normal to the surface of the conductor.
$(b)$ The field lines showed in $(b)$ do not represent electrostatic field lines because the field lines cannot emerge from a negative charge and cannot terminate at a positive charge.
$(c)$ The field lines showed in $(c)$ represent electrostatic field lines. This is because the field lines emerge from the positive charges and repel each other.
$(d)$ The field lines showed in $(d)$ do not represent electrostatic field lines because the field lines should not intersect each other.
$(e)$ The field lines showed in $(e)$ do not represent electrostatic field lines because closed loops are not formed in the area between the field lines.
