• D. Dizziness and fatigue

Answer: (C)

The characteristic symptoms of local inflammation include swelling, redness, heat, and pain. This set of symptoms is often referred to as the classic signs of inflammation and results from the body's immune response to tissue injury or infection.

When inflammation occurs, blood vessels in the affected area dilate, leading to increased blood flow. This causes the area to become red and warm. Additionally, fluid and immune cells leak into the tissue from the blood, which results in swelling. Pain may arise from the release of chemicals that stimulate nerve endings, signaling discomfort and prompting protective behaviors such as rest.

These symptoms work together to localize the injury and begin the healing process, alerting the body to potential threats while facilitating the movement of immune cells to the affected area. Understanding these symptoms is crucial in recognizing inflammation and addressing potential underlying causes.
