चित्र में दर्शाए गए वक्रों में से कौन संभावित स्थिरवैध्यूत क्षेत्र रेखाएँ निरूपित नहीं करते?

$(a)$ 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.
