[USER (data scientist)]: Excellent! Could you generate pie charts illustrating the loan approval rates for specific customer groups: customers aged 40-59, those with stable employment, and those with good or excellent credit history? The loan approval rates are calculated based on the proportion of positive decisions within each customer group. For the stable employment category, include customers who have been employed for 7 years or more, as well as those employed between 4 and 7 years. For the good or excellent credit history category, consider customers with a credit history of 'existing paid', 'no credits/all paid', or 'all paid'. Additionally, could you clarify my following question: If the percentage decrease is 16.77% compared to the age group with the second highest rejection rate, which age group has the highest rejection rate among the following four options?

A. Younger-age group
B. Middle-aged group
C. Older-age group
D. The rejection rate is evenly distributed across all age groups.
E. None of above
