Solution

The correct option is A
A- for series combination and B- for the parallel combination

When resistors are connected in series and parallel, the equivalent resistance in series combination will be greater than the equivalent resistance in parallel combination.

From the graph, we can infer that for a value of potential difference, the current flowing through the circuit B will be more than the current flowing in circuit A. Thus, the resistance in circuit A is more than the resistance in circuit B.

Therefore, in circuit A, resistors are connected in series and in circuit B, resistors are connected in parallel combination.
