Answer: A.
series or parallel
Explanation:
Total resistance across any branch of a circuit can be found by analyzing whether the branch is connected in series or parallel.
The resistors are connected either in series or parallel. Therefore, the resistance of resistors across a circle can be calculated in series and parallel.
