Which signal is the lowering signal?

Explanation:
In signaling, each gesture or command is tied to a specific action, so there’s no ambiguity about what the operator should do. The lowering signal is the command that tells the operator to bring the load down vertically, controlling the descent and speed to keep the load safe. This is distinct from signals for travel (moving the equipment or load along a path), emergency stop (an immediate halt of all movement), and trolley (moving the trolley along the crane bridge). Because lowering the load is a specific, separate action from those others, the option that directly corresponds to the instruction to lower is the correct choice.
