b is the answerrr too yourrr problemmm
the answer is: B.Drowning in underground water
According to OSHA, caught-in or Caught between hazards refers to fatalities that resulted in workers being trapped between two or several things. When you are drowned, you the rescue workers could technically still move around the water area without worrying any collapse might happen, which is why it is categorized differently from caught in or caught between hazards.
