Question

what is your first-choice tool to stop massive bleeding in an arm or leg?
tourniquet
hemostatic/pressure dressing
cravat
gauze

Explanation:

In first - aid for massive bleeding in an arm or leg, the first - choice tool is a hemostatic/pressure dressing. A tourniquet is typically a last - resort option when other methods fail. A cravat is more for making slings or bandages in other first - aid contexts, and gauze alone may not be sufficient for massive bleeding without the pressure - applying aspect of a hemostatic/pressure dressing.

Answer:

B. Hemostatic/pressure dressing (assuming the options are labeled as A. Tourniquet, B. Hemostatic/pressure dressing, C. Cravat, D. Gauze)
