What best illustrates the concept of indirect contact?

The concept of indirect contact refers to a situation where someone interacts with an electrical source without direct physical contact. In this context, using a stick to touch a broken wire demonstrates this concept effectively.

When employing a stick, the individual does not come into direct bodily contact with the live or broken wire. This method serves as an intermediary, providing some measure of safety by reducing the risk of electric shock that would occur if a person touched the wire directly. This illustrates indirect contact well, as the interaction with the electrical hazard is mediated by the stick.

The other options involve scenarios that either present direct contact (like touching a live conductor) or do not directly interact with electricity in a manner that illustrates the concept of indirect contact. For instance, standing near electrical equipment does not entail contact with it, but it does not define an interaction with potential hazards in the same way as using a stick does.
