Answer:

C. They live for only 120 days

Step-by-step explanation:

Red blood cells are small and biconcave cells that are known for their lack of nucleus. (Rules out A) Aside form that, they also lack mitochondria and robsomes. They are created in the bone marrow and they live for about 100 to 120 days (rules out B and D) before macrophages recycle them.
