your answer is B
Osteoarthritis is a type of arthritis that is caused by the breakdown and eventual loss of the cartilage of one or more joints. Cartilage is a protein substance that serves as a “cushion” between the bones of the joints. Osteoarthritis is also known as degenerative arthritis. Among the over 100 different types of arthritis conditions, osteoarthritis is the most common, affecting over 20 million people in the United States
Osteoarthritis occurs when the cartilage normally found in a joint is broken down over time, usually from wear and tear (though they are many other causes of arthritis). So, the answer is B.
