From the electric field lines, we can see that the charges Q₁ and Q₃ are both sources of electric field lines (positive charges), while Q₂ is a sink of electric field lines (negative charge). Thus, the signs of the three charges are positive, negative, and positive, respectively. Choice A is the only one that matches this.
