Abeaker is filled with water. a small plastic container contains a solid bar of aluminum, which has a mass of 40 g, and is placed on the water so that it floats. the water level reads 60 ml. next, the bar of aluminum is taken out of the container and placed in the water so that it sinks to the bottom. the water level in the beaker

Good moring let me you on this question the answer the electric force  have a good day ; )

Ohm's law tells you that i = v/r where v is equivalent voltage and r is equivalent resistance of the circuit
since all circuits have the same voltage, your question is really asking which circuit has the lowest total resistance, since the lower the resistance, the higher the current
circuit a has a resistance of 5 ohms; circuit c is in series so has a resistance of 10 ohms; circuit b is in parallel and therefore has a resistance of 2.5 ohms (review your notes on adding resistances in parallel and series); therefore b has the highest current

Ibelieve the answer is d. macula  hope my answer has you : )
