​​​​Consider a lossless transmission line terminated with a short circuit as shown in the figure below. As one moves towards the generator from the load, the normalized impedances $z_{\text {inA }}, z_{i n B}, z_{i n C}$, and $z_{i n D}$ (indicated in the figure) are $\_\_\_\_\_\_.$

  1. $z_{i n A}=+1 j \Omega, z_{i n B}=\infty, z_{i n C}=-1 j \Omega, z_{i n D}=0$
  2. $z_{\text {inA }}=\infty, z_{\text {inB }}=+0.4 j \Omega, z_{\text {inC }}=0, z_{\text {inD }}=+0.4 j \Omega$
  3. $z_{i n A}=-1 j \Omega, z_{i n B}=0, z_{i n C}=+1 j \Omega, z_{i n D}=\infty$
  4. $z_{i n A}=+0.4 j \Omega, z_{i n B}=\infty, z_{i n C}=-0.4 j \Omega, z_{i n D}=0$
