for combination (A) the equivalent resistance is
Re = R+1/(1/R+1/R)=1+1/2 = 1.5 ohms
For combination B the equivalent resistance is
Re = 1/(1/3R+1/3R )=1/(1/3+1/3) = 3/2 = 1.5 ohms
So the answer is
Both (A) and (B)

Learning Goal:
To learn to calculate the equivalent resistance of the circuits
combining series and parallel connections.
Resistors are often connected to each other in electric
circuits. Finding the equivalent resistanceof
combinations of resistors is a common and important task.
Equivalent resistance is defined as the single resistance that can
replace the given combination of resistors in such a manner that
the currents in the rest of the circuit do not change.
Finding the equivalent resistance is relatively straighforward if...
