Correct Answer

capacitive

Explanation

l < ?/4, Z_L = 0

The input impedance of short-circuited line of length l where ?/4 < l < ?/2, is resistive inductive , if Z_d comes +j kZ_C then inductive,

If Z_d comes -j kZ_C then capacitive.

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

The input impedance of short-circuited line of length l where ?/4 < l < ?/2, is resistive inductive
