There should be options for this question. I found them elsewhere online.
More than 50 percent of electrocutions are caused by a worker coming in direct contact with:
A. Energized power lines
B. Power tools with metal parts that have become energized
C. An electric fence
D. An underground utility that was not deenergized by the utility company
The correct answer is A. Energized power lines
Workers are coming into contact with overhead and underground power lines. Overhead lines are typically not insulated. Any covering is generally a weather protection, not insulation. Underground power lines can be damaged and exposed.
