The correct answer is B) Hoist CL tackline IW. The key reason this is the correct answer is that when signaling by flag hoist using the International Code of Signals, the signals are read in the order they are hoisted from top to bottom. By hoisting CL first and then IW tackled below it, the signals will be read in the correct order as requested, with CL first and then IW. The other options are incorrect because: A) Hoisting CLIW together would not preserve the order, as the signals would be read as a single unit. C) Hoisting the signals from different yards would not maintain the proper order of reading. D) Not all of the options would ensure the correct reading order.
