Low Frequencies are used to locate what?

Explanation:
Low frequencies create a tracer signal that travels along buried conductive lines when it’s injected via a direct connection. This lets a receiver detect and follow the signal down the route of the utility, making it ideal for locating cables and insulated pipes even when they’re buried or covered. Other options don’t fit because shielding a power grid, testing fiber optic cables, or measuring soil moisture rely on different techniques or signals that aren’t used to trace buried conductive lines.
