Which type of fire is best represented by 'grazing fire'?

Grazing fire is characterized by the bullet trajectory being relatively low and close to the ground, making it effective against targets that are relatively flat and in a defined area. The optimal range for grazing fire is generally understood to be effective at distances up to about 600 meters. At this range, the bullets travel in a trajectory that remains low enough to maintain its effectiveness, allowing for a greater impact on targets without hitting the ground. Beyond this range, the effectiveness of grazing fire diminishes as the arc of fire increases and the likelihood of hitting targets decreases.

While other distances listed in the choices represent ranges for different types of fire, grazing fire is specifically designed for close engagement with the terrain and adversary positions, which is why 600 meters is the most appropriate representation in this context.
