A transmission line of characteristic impedance $50 \; \Omega$ is terminated in a load impedance $Z_L .$ The VSWR of the line is measured as $5$ and the first of the voltage maxima in the line is observed at a distance of $\lambda / 4$ from the load. The value of $Z_L$ is

1. $10 \; \Omega$
2. $250 \; \Omega$
3. $(19.23+j 46.15) \; \Omega$
4. $(19.23-j 46.15) \; \Omega$
