You are signaling by flag hoist using the International Code of Signals. You wish to send the signals CL and IW and have them read in that order. What would ensure this?

Correct Answer: Option B — Hoist CL tackline IW

Using a tackline between distinct flag groups ("CL tackline IW") physically separates the hoists on the same halyard, ensuring they are read sequentially as intended rather than interpreted as a single combined multi-letter signal.
