Distance between mortars and safety shelter on a floating vessel is determined by which of the following?

Explanation:
On a floating vessel, the space between the mortar and the safety shelter is set based on how big the shell is, because bigger shells can cause more blast, heat, and flying fragments. The rule uses a scale: if the shell’s diameter is less than six inches, you need a distance of two times the diameter (in feet) between the mortar and the shelter; if the shell’s diameter is larger than six inches, you need a distance of four times the diameter (in feet). This means larger shells require a much greater clearance to protect crew in case of a misfire, shell rupture, or other mishap. For example, a shell under six inches would need at least two times its diameter in distance, while an eight-inch shell would need at least four times its diameter, which is a much larger gap. The other options don’t scale the distance with shell size in this protective way, so they don’t provide adequate protection across different shell diameters.
