Match List-I with List-II for a transmission line with a series impedance Z = R + jωLΩ/m and a shunt admittance Y = G + jωC mho/m, and select the correct answer:

List-I (Parameters)	List-II (Values)
a. Characteristic impedance Z0	1. $$\sqrt {{\text{ZY}}} $$
b. Propagation constant γ	2. $$\sqrt {\frac{{\text{Z}}}{{\text{Y}}}} $$
c. The sending-end input impedance ZS when the line is terminated in its characteristic impedance Z0	3. $$\sqrt {\frac{{\text{Y}}}{{\text{Z}}}} $$
