Which of the following can help identify overhead powerlines?

Choosing tiger tails as a means to identify overhead powerlines is correct because they are specifically designed for this purpose. Tiger tails are brightly colored plastic or fabric markers that are suspended from the power lines and serve as visual warnings. They help ensure that people are aware of the presence of overhead electrical lines, especially in locations where working near such hazards is common.

Fluorescent tape could be useful in various situations for marking or signaling but is not specifically intended for designating overhead powerlines and does not provide the same level of visibility from below. Traffic cones are primarily used for directing traffic and marking hazards on the ground, and they do not offer any indication of overhead dangers. Safety goggles are necessary for protecting the eyes from potential hazards on a worksite, but they do not relate to identifying overhead powerlines in any way.
