Which circuit shows three non-identical resistors with the same current?

The correct answer is option (c).

In figure, all the three resistances are in series combination. And, In a series connection, the current is same in the branch i.e. all the resistances will have the same current.

And, in the parallel combination, all the resistances have same voltage but different current values. Hence, option (c) is the correct answer. 

The correct answer is c
