The correct answer is B) General arrangement. The vessel's fire control plan is typically laid out on the general arrangement plan, which is a detailed diagram of the vessel's layout and key features. The general arrangement plan includes the location of fire detection and suppression equipment, escape routes, and other critical safety information. This plan is essential for understanding the vessel's fire safety systems and procedures. The other answer choices are not correct because: A) Midship section - This plan shows the cross-section of the vessel at the midpoint, and does not typically include the fire control information. C) Subdivision - This plan shows the vessel's internal compartments and bulkheads, but does not specifically depict the fire control equipment. D) Lines - This plan shows the vessel's hull shape and dimensions, without including the fire safety details.
