**Explanation for Calculation**

To calculate the minimum wire size needed to limit the voltage drop to less than 3%, you would typically use the formula for voltage drop:

Voltage Drop = (2 x K x L x I) / CM

Where:

K is the resistivity of the wire material (for copper, it’s approximately 12.9)

L is the length of the wire in feet (100 feet in this case)

I is the current in amperes (which would depend on the load but is not provided in the question)

CM is the circular mil area of the wire

The question asks for the minimum wire size to limit the voltage drop to less than 3% of 240V, which is 0.03 x 240 = 7.2V.

To find the minimum wire size, you would rearrange the formula to solve for CM (circular mil area), and then refer to a wire size table to find the corresponding American Wire Gauge (AWG) size.

Since the question is multiple-choice and designed to test your understanding of the principles rather than exact calculations, you would select the wire size that is commonly known to meet the less than 3% voltage drop criteria for a 240V circuit of 100 feet, which is 6 AWG.
