The right answer is C.
During inflammation, under the influence of chemical mediators, endothelial cells (forming the blood vessels) become activated. This leads to local arteriolar vasodilation then capillary2 which causes:
** an increase in blood supply
** a decrease in the speed of blood flow
This local swelling of the blood vessels causes redness and the sensation of heat. It aims to increase the flow of blood to evacuate dead cells and toxins (detox) and provide the elements necessary for healing, including white blood cells to fight against foreign bodies.

Explanation:
Flagella are organelles defined by function rather than structure.
The primary function is that of locomotion but also being sensitive to chemicals and temperatures outside the cell.
Helicobacter pylori is a good example of flagella: It uses multiple flagella to propel itself through the mucus lining to reach the stomach epithelium.
Sperm cell is a good example, which uses its flagellum to propel itself through the reproductive tract of females.
