Final answer:
Inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis, is treated with immunosuppressants, such as corticosteroids, azathioprine, and methotrexate. Antivirals are not commonly used to treat IBD.
Step-by-step explanation:
Inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis, is treated using immunosuppressant medications. These medications work by suppressing the body's immune response, which helps to reduce inflammation in the intestines and alleviate symptoms.
Examples of immunosuppressant medications commonly used in the treatment of IBD include corticosteroids (e.g., prednisone), azathioprine, and methotrexate. These medications can help to control inflammation and prevent flare-ups of the disease.
Therefore, the correct answer to the question is d) Antivirals. Antivirals are a type of medication used to treat viral infections, and they are not typically used in the treatment of IBD.
