Explain the modifications to these laws made in the general and special theories of relativity
THE LAW OF CONSERVATION OF MASS
AND THE LAW OF CONSERVATION OF ENERGY

You can find results and justify them? you can test your hypothesis

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 answer is don't know.
