[USER (data scientist)]: We aim to examine the influence of different court surfaces on the performance of players in the ATP tennis dataset, categorized by their rankings: top, mid, and low. Our method involves a Stratified Analysis, incorporating charts and statistical tests (p-values) to compare performance across these ranking groups and court surfaces. The top-ranked players are those in the 0-50 range, mid-ranked players fall within the 50-200 range, while any ranking beyond that is considered low. Additionally, could you provide insight into how the win/loss ratio distribution changes with different court surfaces, as indicated in the chart? 

A. significantly
B. slightly
C. not at all
D. None of above
