GATE EC 2026 Set 1 Q42 — Transmission Lines

A complex load (in $\Omega$ ) is represented as $\Gamma_{L}=0.5 \angle 30^{\circ}$ on the Smith chart. A co-axial cable with a characteristic impedance of $50 ~\Omega$ is connected to the load. The new input impedance of the load now moves to a diametrically opposite point on the same $\Gamma$ circle on the Smith chart.

Which option is the nearest input impedance of the cable connected load (in $\Omega)?$
