Answer: Option B
Step-by-step explanation:
The body functions properly under proper temperature and pH. If the temperature of the body drops down too low or gets too high then it should be regulated by the homeostasis of the body else the body will not function properly.
In case, the body is not able to regulate the temperature of the body then the body will not function properly and the body organs will stop working.
Hence, the correct answer is option B.
