The symbol “A” in column 1 indicates hazmat rules apply primarily when transported by which mode?

Explanation:
The symbol in column 1 flags the mode for which hazmat rules apply primarily. When that symbol denotes air, it means the hazmat requirements are mainly driven by aviation safety, so you must follow the air transport rules (such as IATA/ICAO standards and any FAA/related regulations) that govern packaging, labeling, quantity limits, and handling. This is why the air option is the best answer—the marker points specifically to air transport as the primary concern for hazmat rules. The other modes have their own separate considerations and aren’t indicated by this symbol.
