6.
The input impedance of short-circuited line of length l where λ/4 < l < λ/2, is
resistive
inductive
capacitive
none of the above
Answer: Option
Explanation:

l < λ/4, ZL = 0

, if Zd comes +j kZC then inductive,

If Zd comes -j kZC then capacitive.

for 0 ≤ l ≤ 1/4, λ ≤ l ≤ 3λ/4 will be inductive.

b(beta) = 2*π/λ.
if d = λ/4 implies Zd = 0.
Calculate like this you will find the answer.
