Answer Key / Explanation : (d) -
(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
