The answer is the first one: $\beta$-Interferon.

Explanation for each option:

1. $\beta$-Interferon: This is the correct answer. $\beta$-Interferon is a type of cytokine that is commonly used in the treatment of multiple sclerosis (MS). It helps to modulate the immune system and reduce inflammation, which can decrease the frequency and severity of MS relapses.

2. Interleukin-2: This cytokine is primarily used to treat certain types of cancer, such as renal cell carcinoma and melanoma. It is not typically used for multiple sclerosis treatment.

3. Erythropoietin: This cytokine is used to stimulate the production of red blood cells and is commonly used in the treatment of anemia, particularly in patients with chronic kidney disease. It is not used for multiple sclerosis.

4. Colony-stimulating factor: These cytokines are used to stimulate the production of white blood cells and are often used in patients undergoing chemotherapy to prevent infections. They are not used for the treatment of multiple sclerosis.

In summary, $\beta$-Interferon is the cytokine used in the treatment of multiple sclerosis.
