Final answer:
Cervical conditions affect different age groups starting from CIN, commonly occurring in ages 20-30, CIS likely in 31-40, and Cervical Cancer most common in those over 60 years old. Thus, the most accurate age groupings are: CIN at 20-30 years, CIS at 31-40 years, and Cervical Cancer at over 60 years.
Step-by-step explanation:
The question appears to be about the most common age groups affected by various stages of cervical conditions: Cervical Intraepithelial Neoplasia (CIN), Carcinoma in Situ (CIS), and Cervical Cancer. Based on the provided data and what is known about these conditions, we can infer the following common age ranges:
- For CIN, which is a precancerous condition, the most commonly affected age group is 20-30 years. This coincides with the highest percentage of people diagnosed (75%) according to the table.
- For CIS, which is a localized cancer cell growth, the most commonly affected age group likely falls between 31-40 years, given the data and typical progression from CIN.
- For Cervical Cancer, which is an invasive disease, the commonplace age group is more than 60 years. This agrees with cancer's tendency to develop over time and the importance of early detection in younger age groups.
Therefore, the correct answer to the original query would appear to be option a): 20-30; 35-45; 50+.
