**(a)**

Equivalent circuit of the given circuit is

Between points C and D resistors 2 , 2 and 2 are in series, therefore, their equivalent resistance,

Resistors R’ and 6 are in parallel, therefore their equivalent resistance is given by

Now between points A and B 1 , 3 and 1 are in series.

Therefore, resultant resistance is

R=1+3+1=5
