For the three-bus lossless power network shown in the figure, the voltage magnitudes at all the buses are equal to 1 per unit (pu), and the differences of the voltage phase angles are very small. The line reactances are marked in the figure, where α, β, γ, and x are strictly positive. The bus injections P₁ and P₂ are in pu. If P₁=mP₂, where m>0, and the real power flow from bus 1 to bus 2 is 0 pu, then which one of the following options is correct?
