Final Answer :
B
Explanation :
The redness and heat observed in an inflamed area are primarily due to increased blood flow to the area. This is a part of the body's inflammatory response to injury or infection, where blood vessels dilate to allow more blood, along with immune cells and nutrients, to reach the affected area, facilitating healing and defense.
