Acircuit consists of a parallel-plate capacitor, an inductor, and a switch, which is initially open. the capacitor plates have an area of 1.00 × 10−4 m2 and are held 0.100 mm apart by a thin layer of barium titanate. the capacitor is charged to a potential difference of 14 v , and then the switch is closed. how much charge remains on the capacitor at the instant the energy stored in the inductor has increased to 80 % of its maximum?

Ithink it is letter b, i may be wrong but i think that is the 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

Wow good luck with that answer

Answervery high orbital velocities in a very compact region;
