The correct answer is D) Cool the bottles or remove them from the fire area. When fighting fires in spaces containing LPG bottles, the priority is to prevent the bottles from being exposed to excessive heat, which could cause them to rupture or explode. Cooling the bottles or removing them from the fire area is the appropriate action, as it helps maintain the structural integrity of the bottles and prevents a potentially catastrophic incident. The other options, while important safety measures in other fire scenarios, do not directly address the unique hazards posed by LPG bottles in a fire.
