2.
The input impedance of short-circuited line of length l where l < λ/4
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.

Remember for the SC line it is jz0 tan bl which is positive and it is inductive because the inductor has positive reactance and for the open circuit, it is - jz0cot bl.
