When inspecting a fire extinguisher: a) the seal should not be broken b) the safety pin should be removed for easier use c) the unit should be out of the way and out of reach d) the gauge should read at least 1/4 full or be only slightly "in the red"

I believe it’s B, so that you do not accidentally spray out of the hose

The correct answer is  A) The seal should not be broken

The seal of the fire extinguisher is a proof that the fire extinguisher has not been tampered with or used since the last inspection or service before. Also, it keeps the safety pin from getting loose or accidentally falling out. In the absence of that safety pin, the extinguisher could possibly be discharged or triggered. The seal also contain a date indicating the last time it was inspected.

yes, but you must first make sure that you'll be able to make your turn or you can crash into other vehicles.
