Which color line indicates Electric?

Which color line indicates Electric?

• A. Red
• B. Blue
• C. Green
• D. Electric

Answer: (D)

The main idea here is using labeling to identify service types on diagrams. In field drawings, color helps group different services, but you need a clear label to know which line is Electric. The line that explicitly says “Electric” leaves no doubt about which service it represents. Colors like Red, Blue, or Green could correspond to other services in the legend, but without the label, they don’t definitively indicate Electric. So the best choice is the line that is labeled Electric, because the label directly identifies the utility service.
