Detailed Solution

Concept: On a modest positive test charge, an electric field line depicts the force's direction. The field line does not form a closed loop because the test charge does not typically return to where it started.
Positive charge is where electric field lines begin (or diverge) and end (or converge) before reaching negative charge. Electric field lines always flow from positive to negative, making it impossible for them to form a closed loop where the lines must both start and terminate on the same charge.
The absence of an electric field line inside the charged body is the primary cause of the electrostatic field lines failing to form a complete loop. Therefore, we assert that closed loops never exist in electrostatic field lines.
Hence, option 1 is correct.
