In the circuit shown in the figure,four identical resistors labeled A to D are connected to a battery as shown.S₁ and S₂ are switches.Which of the following actions would result in the GREATEST amount of current through resistor A? A)closing both switches B)closing S₁ only C)closing S₂ only D)leaving both switches open as shown.

Closing both switches would create a parallel circuit for resistors A and C, and another parallel circuit for resistors B and D. This would result in the lowest total resistance and therefore the greatest amount of current flowing through resistor A.
