Answer:

a. inflammatory response

Explanation:

In medicine, an inflammatory response takes place when tissues of our body are injured (either by a physical trauma, heat, bacteria, virus). When our cells detect they are being hurt they release some chemicals to protect the body. These chemicals that are released cause blood vessels to leak fluid into the hurt tissues and therefore, the tissue becomes red, warm (because of the movement of fluids) and it also produces swelling.

In this example, a boy falls while riding his bike and a scrape on his hand begins to bleed and becomes red, warm and swollen. We can see that he suffered a trauma (the fall) and this fall caused a scrape on his hand (body injured), therefore, the body is releasing chemicals to protect the body, and this is causing the skin to become red, warm and swollen. Thus, this is an example of an inflammatory response.
