This one is complicated. Not hard, but several steps. The two 5-ohm resistors in series have a total resistance of 10 ohms. 1.6 A through 10 ohms means the battery is (1.6 x 10) = 16 volts. Then ... 16 volts produces 2A of current through (16/2) = 8 ohms of resistance. If 3 identical resistors in parallel look like like 8 ohms, then each one is (8 x 3) = 24 ohms. That's D.
