The law of superposition is a/an select one: a. creative method to date rocks. b. unreliable method to date rocks. c. biased explanation for how rocks were formed. d. elaborate explanation for how rocks were formed.

The correct option is A.
The law of superposition is a basic law in geology which explain how rocks are arranged in layers according to their age. The law states that in undisturbed layers of rocks, the youngest rock is always on the top while the oldest rock will be at the bottom in accordance with their occurrence. The law is used in geology to predict the age of rocks.

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
