A special wrench for the couplings in a fire hose line
B cross connection line between two main fire lines
C tackle rigged to support a fire hose
D None of the above
AI Explanation

The correct answer is A) a special wrench for the couplings in a fire hose line. A spanner is a type of wrench specifically designed to tighten or loosen the couplings that connect fire hose sections together. This specialized tool is essential for maintaining and operating a ship's fire suppression system, as it allows crew members to quickly and securely assemble and disassemble the fire hose lines as needed. The other answer choices are incorrect because they do not accurately describe the function of a spanner. Options B and C refer to different components of a fire suppression system, but do not match the definition of a spanner. Option D is a catch-all choice that is incorrect since the previous options have provided the proper definition of a spanner.
