Which of the following is NOT a Large Diameter hose size?

Explanation:
LDH refers to hoses used for high-volume water supply, typically larger diameter lines used to move water from hydrants or pumpers to the scene. In this training context, large diameter hose sizes start at 4 inches and include sizes like 4 inches and 6 inches. The 3-inch option is treated as not being a Large Diameter Hose in this question, which is why it’s identified as the correct choice for NOT being LDH. The 4-inch and 6-inch sizes are classic LDH, while the 2 1/2 inch size is a standard handline, not LDH.
