I say A
I wouldn't there doesn't seem to be an air way problem. So I would do a head to toe assessment to see if there is any injury to the person and to see if there is an air way problem. I hope that makes sense.
Choking or he is having a hard time breathing
I would say after about 5-10 minutes.
Hope this helps!
