Assertion (A) The effective resistance of the network between P and Q is\[\text{IIIIII}\]. Reason (R) Symmetry can be applied to the network with respect to centre. Each of these questions contains two statements. Assertion and Reason. Each of these questions also has four alternative choices, only one of-which is the correct answer. You have to select one of the codes (a), (b), (c) and (d) given below.

A) If both Assertion and Reason are true and Reason is correct explanation of Assertion.

C) If Assertion is true but Reason is false.

D) If both Assertion and Reason are false.

Correct Answer: D

Solution :

The given circuit can be redrawn as considering the symmetry of the circuit, points S and T can be separated as shown below. Thus,                     \[({{f}_{pn}})\]
