(D)There is more blood circulation to the skin to release heat from the body.

Answer 1

Hint: The reddish tinge of the skin is due to increases in body fluid containing red blood cells and a person feels fever when the body emits heat when it feels that there is some infection present.

Complete answer:
When a person is suffering from high fever the skin has a reddish tinge because there is more blood circulation to the skin to release heat from the body. The person suffers from fever because the hypothalamus release fever-producing chemicals that change body temperature in response to different factors, such as infectious organisms and injury.

Additional Information: A fever can be caused due to many medical conditions which can be non-serious and even can be life-threatening.
The conditions when a person has fever include viral, bacterial, and parasitic infections for example influenza, the common cold, meningitis, urinary tract infections, COVID-19, malaria, and many more. Fever can be diagnosed even when there is no infection. For example in vasculitis, deep vein thrombosis, connective tissue disease, side effects of medication, and cancer. Treatment of fever depends on the main cause of your fever. If the fever is very high, the doctor may recommend taking an over-the-counter medicine such as acetaminophen or paracetamol. Adults can also take aspirin. It is also important to drink enough liquids, to prevent the body from dehydration.
So, the correct answer is ‘There is more blood circulation to the skin to release heat from the body.’

Note: The average normal body temperature is generally accepted as ${ 37 }^{ \circ }{ C }$. A temperature over ${ 100.4 }^{ \circ }{ F }$ which is ${ 37 }^{ \circ }{ C }$ most often means you have a fever which is a sign or symptom of an infection or illness.
