Which of the following configurations can be used to create a Wheatstone bridge?

Which of the following configurations can be used to create a Wheatstone bridge?

Step 1: Understand that a Wheatstone bridge is a circuit used to measure unknown resistances.
Step 2: Know that it consists of four resistors arranged in a diamond shape.
Step 3: Identify that two resistors are in series on one side and two resistors are in series on the other side.
Step 4: Recognize that a galvanometer (a device to measure current) is connected between the two junctions of the series resistors.
Step 5: Realize that the bridge is balanced when the ratio of the two resistors on one side is equal to the ratio of the two resistors on the other side.
