PLEASE HELP A child and sled with a combined mass of 55.7 kg slide down a frictionless hill that is 11.3 m high at an angle of 29 ◦ from horizontal. The acceleration of gravity is 9.81 m/s2. If the sled starts from rest, what is its speed at the bottom of the hill?
Answer in units of m/s.

Indoraptor for sure

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
