The transmission line of charecteristic impedance 50 Ω and feeding a purely resistive load of 200 Ω uses single quarter wavelength long short circuit stub which is placed at a distance d from the load .The VSWR on the transmission line section of length d and VSWR on the stub respectively are

A

O and O respectively

B

1 and 1 respectively

C

4 and 1 respectively

D

4 and $$\infty$$ respectively
