For the balanced 3-phase transmission line shown, consider the following cases:
Case-1: $\left|V_1\right|=1.1$ p.u., $\left|V_2\right|=0.9$ p.u., $Z=0.75 \angle 0^{\circ}$ p.u. and $\theta_{12}=\theta_1-\theta_2=0^{\circ}$
Case-2 : $\left|V_1\right|=1.1$ p.u., $\left|V_2\right|=0.9$ p.u., $Z=0.75 \angle 90^{\circ}$ p.u. and $\theta_{12}=\theta_1-\theta_2=90^{\circ}$

Which of the following statements is/are correct about real power loss and reactive power loss in the line?
In the figure shown, self-impedances of the two transmission lines are $1.5 j \mathrm{pu}$ each and $Z_m=0.5 j \mathrm{pu}$ is the mutual impedance. Bus voltages shown in the figure are in pu. Given that $\delta>0$, the maximum steady state real power that can be transferred in pu from bus- 1 to bus- 2 is
