Answer:
B- Call 9-1-1 or the designated emergency number.
Step-by-step explanation:
The first thing to do is call 911 or the designated emergency number. The person needs professional assistance that can help him and check the severity of his hypothermia. The sooner we call the emergency number, the fastest the help will arrive, which is very important since time has a crucial role in these types of cases. Once you call 911, they will tell you what to do while they are on their way, something that is very important because if we do not follow their instructions, we can harm the person.
