d) Classes 6, 7, and 9

Answer 1

The correct hazard classes that should not be loaded into a trailer with a heater or AC unit are Classes 2, 3, and 4.

Step-by-step explanation:

The correct answer is a) Classes 2, 3, and 4. Hazard classes 2, 3, and 4 refer to gases, flammable liquids, and flammable solids, respectively.

Heaters and AC units inside a trailer can pose a risk of ignition or explosion for these hazardous materials.

For example, if a flammable liquid is present in the trailer and the heater malfunctions, it could cause the liquid to ignite, leading to a fire or explosion.
