I’m leaning towards Option C since it looks familiar, but I’m a bit confused about how the percentages are applied in the code.

I feel like Option B might be the right choice because it mentions using a stratified sampling method, but I need to double-check the percentages.

I think the key here is the stratification by county, but I'm not sure which option actually implements that correctly.
