When determining the percentage of people with Hepatitis C who are likely to develop chronic hepatitis and cirrhosis, we rely on available medical data.
Based on the data, approximately 75% of people with Hepatitis C are at risk of progressing to chronic hepatitis and cirrhosis. Let's break this down:
1. Hepatitis C is a viral infection that can lead to severe liver damage.
2. Over time, if left untreated, Hepatitis C can result in chronic hepatitis, which is a long-term inflammation of the liver.
3. Further progression can lead to cirrhosis, which is the scarring of the liver tissue due to continuous long-term damage.
Thus, based on these considerations, the percentage of people with Hepatitis C likely to develop chronic hepatitis and cirrhosis is:

Therefore, the correct option is:
O 75%
