The correct option is C
Drawing VThe electric field lines comes out from a positive charge and goes into a negative charge .
fig. (1) shows closed field lines , which is impossible.
fig. (2) shows two positive charges , because field lines are coming out from both the charges and showing repulsion.
fig.(3) shows a single positive charge.
fig.(4) shows a uniform electric field from a positive plate to a negative plate.
fig.(5) shows a positive and negative charge (two unlike charges) , because field lines are coming out from a charge ( positive) and going into another charge (negative).
