An astronomical unit (AU) is a scientific measurement between objects in space. Scientists decided that 1 AU would represent the distance from the Earth to the Sun, about 150 kilometers. Using this information, which objects would exert the strongest gravitational force on each other? A. two objects of the same mass that are 0.08 AU apart
B. two objects of the same mass that are 5 AU apart
C. two objects of the same mass that are 1 AU apart
D. two objects of the same mass that are 12 AU apart

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
