To solve this question, we need to understand what is meant by a wire being described as having a metric size of 2.0.
In the context of wires, the metric size typically refers to the cross-sectional area of the wire, which is commonly measured in square millimeters (mm²).
Given the metric size is 2.0, this indicates that the cross-sectional area of the wire is 2.0 square millimeters (mm²).
Among the given choices:
a. 2.0 mm (square) cross-sectional area.
b. 2.0 cm (square) cross-sectional area.
c. 2 inch (square) cross-sectional area.
d. 0.2 mm (square) cross-sectional area.
Choice a, 2.0 mm (square) cross-sectional area, is the correct one.
So, the wire described as having a metric size of 2.0 means it has a cross-sectional area of 2.0 mm². Therefore, the correct answer is:
a. 2.0 mm (square) cross-sectional area.
