Hi, I would like to reassure my concept on this question. I have 2 different ways to solve this question:

1) Determining the direction of current in the loop using right-hand solenoid loop and adding them up to get 2I. With option C as the answer.

2) Because all the wires are in 1 closed loop with the same direction, we should just add them up together to get a total of 6I. With option E as the answer.
