Match the items in List-$$I$$ (Type of transmission line) with the items in List-$$II$$ (Type of distance relay preferred) and select the correct answer using the codes below the lists.

List-$$I$$
$$A.$$ Short Line
$$B.$$ Mesium Line
$$C.$$ Long Line

List-$$II$$
$$1.$$ Ohm Relay
$$2.$$ Reactance Relay
$$3.$$ Mho Relay

$$A = 2,\,\,B = 1,\,\,C = 3$$

$$A = 3,\,\,B = 2,\,\,C = 1$$

$$A = 1,\,\,B = 2,\,\,C = 3$$

$$A = 1,\,\,B = 3,\,\,C = 2$$
