The histogram shows final exam scores, and the table shows letter grades for each range of scores. A passing grade is 60% or higher. A 90–100%
B 80–90%
C 70–80%
D 60–70%
Which statement is supported by the data in the histogram?
A. Twenty students received As and Bs.
B. Forty students received scores between 40% and 60%.
C. Most students received As and Bs.
D. Most students passed the final exam.

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
