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 $z_{inA}$, $z_{inB}$, $z_{inC}$, and $z_{inD}$ (indicated in the figure) are _________.

$z_{inA}=+1j \Omega$, $z_{inB}=\infty$, $z_{inC}=-1j \Omega$, $z_{inD}=0$

$z_{inA}=\infty$, $z_{inB}=+0.4j \Omega$, $z_{inC}=0$, $z_{inD}=+0.4j \Omega$

$z_{inA}=-1j \Omega$, $z_{inB}=0$, $z_{inC}=+1j \Omega$, $z_{inD}=\infty$

$z_{inA}=+0.4j \Omega$, $z_{inB}=\infty$, $z_{inC}=-0.4j \Omega$, $z_{inD}=0$
