A hose laid from the fire to the hydrant is considered a:

The scenario describes a hose layout from the fire to the hydrant, which indicates that the hose is being used to supply water from the hydrant to the location of the fire. This is characteristic of a reverse lay, where the hose is deployed back to the source of water (the hydrant) while the firefighters are positioned at the fire scene.

In a reverse lay, the first section of hose is connected at the fire scene and then laid back to the water source. This allows for a continuous flow of water to the fire while minimizing the distance that firefighters need to travel with the hose. It is particularly useful in situations where the fire is further away from the hydrant and efficient water delivery is crucial.

The choice of a forward lay refers to laying hose from the water source to the fire, which is not applicable in this case. The supply line refers specifically to the hose that connects the water source to the engine or pump, but does not describe the directionality involved in this situation. An attack line is utilized for applying water directly to the fire, which also does not apply because the hose in question is not being used for that purpose in this context.
