From a solution of wave equation in a conducting medium we can determine various parameters. In the light of this, match List-I with List-II and select the correct answer using the options given below the lists:

List-I (Parameter)	List-II (Expression)
a. Propagation constant	1. $${\left( {\frac{2}{{\omega \mu \sigma }}} \right)^{\frac{1}{2}}}$$
b. Skin depth	2. $${\left( {\frac{{\omega {\mu _0}}}{{2\sigma }}} \right)^{\frac{1}{2}}}$$
c. Sheet resistance	3. $${\left( {j\omega {\mu _0}\sigma } \right)^{\frac{1}{2}}}$$
	4. $${\left( {\frac{{\omega {\mu _0}\sigma }}{2}} \right)^{ - \frac{1}{2}}}$$
