The correct option is B. It regulates body temperature.
<h3>What is homeostasis?</h3>
In biology, homeostasis is the condition of steady internal, physical, and chemical requirements maintained by living systems.
- This is the requirement of optimal functioning for the organism and contains many variables, such as body temperature and fluid balance, being kept within certain pre-set limitations (homeostatic range).
- Other variables include the pH of extracellular fluid, the engagements of sodium, potassium, and calcium ions, as competently as the blood sugar level, and these need to be regulated despite changes in the atmosphere, diet, or level of activity. Each of these variables is controlled by one or better controllers or homeostatic mechanisms, which together maintain life.
- Homeostasis exist obtained about by a natural resistance to switch when already in the optimal conditions, and balance is maintained by many regulatory mechanisms.
- All homeostatic control mechanisms include at least three interdependent elements for the variable being regulated: a receptor, a control center, and an effector.

DNA (Deoxyribonucleic Acid) is found in the Nucleus hence why it is called the control center of the cell.
Answer: Blood is slightly more viscous then water, pH is slightly alkaline it is about 8% of ones body total body weight the rest of the options are slightly wrong.
Explanation: Blood is red in colour, a dark red when it is deoxygnated and bright red when oxygenated. Its normal pH is 7,4 making it slightly alkaline and it accounts for 8% of one's total body weight with 92% being water. Its temperatures ranges around our normal body temperature which is 37°C.
