Amotorist pulled over for running a red light claims that because, of his speed, the 630 nm red light appeared to be 530 nm green light. the traffic cop, who happens to have a physics degree, cites the motorist both for running the red light and for another traffic violation. what is the other traffic violation? your answer should be supported by a quantitative calculation with a correct result.

Is this a question of an answer

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

The sun's gravitational pull is weaker on the planets that are closer to it, i think.

Amicroscope, because these cells are so small that you would not be able to see them, or what they attack without it.
