**(d)**

The be the total resistance of infinite network of resistance connected to points and . Therefore the addition of one step of resistances in the infinite network of resistances will not change the total resistance of the network. Therefore equivalent circuit will be as shown in figure. Then total resistances between ’ and ’ is given by

or

Since negative value of is not possible
