Answer
Carries oxygen around the body and removes carbon dioxide and waste products.
Explanation
## Step1: The role of red blood cells in the human body is to transport oxygen from the lungs to the various cells within the body and remove waste products like carbon dioxide. ## Step2: Hence, the first option matches the description having 'Carries oxygen around the body and removes carbon dioxide and waste products'.## Step3: The other option that mentions 'Helps to fight infection' is a moving understanding of red blood cells because from our experiences of our understanding, we could likely predict this role to correspond more typically to white blood cells. ## Step4: Lastly, 'Helps the blood to clot' is largely due to the work of platelets and is therefore not a main function of red blood cells.
