A transmission line of characteristic impedance $50 \; \Omega$ is terminated in a load impedance $\text{Z}_\text{L} .$ The $\text{VSWR}$ 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 $\text{Z}_\text{L}$ is
- $10 \; \Omega$
- $250 \; \Omega$
- $(19.23+j 46.15) \; \Omega$
- $(19.23-j 46.15) \; \Omega$
