Hi Belle, I think it would be Intensity because the beats per minute are increasing. So that means that she/he is going faster. I hope this helped!!!
I need more info to answer this question
Why are health care workers at high risk for back injury and musculoskeletal injury while moving and transferring patients.
These injuries are due in large part to overexertion related to repeated manual patient handling activities, often involving heavy manual lifting associated with transferring, and repositioning patients and working in extremely awkward postures.
Its got to be B because A is not right all the way and it doesn't provide feedback it would have to make the body do things.
