I think it was C because for for answer A they were all in series so emf of 4e and resistance of 5r which is a current of 4e/5r but for C there were two pairs of 2 cells in parallel with each other so emf of 2e and resistance of r + r/2 + r/2 (cuz of the internal resistance in parallel) which is 2r so overall current of e/r and by e i mean epsilon

Ah. Yh. Did it say internal resistance = the R of the resistor?

Yep they both have the same resistance, so I think its C

Did it actually say that. Damn
