It is internally invalid unless categories overlap: the colors look unattractive, not because the parts total 120%. Change the colors but keep the exclusive 120% total.

It is internally invalid unless categories overlap: exclusive pie parts cannot total 120%. Make categories sum to 100% or label a multiple-response design.

It is internally invalid unless categories overlap: every pie chart is invalid regardless of its total. Ban the display rather than repair the category definitions.

It is valid because the percentages are printed, even though categories are declared exclusive: exclusive pie parts cannot total 120%. Keep the 120% exclusive pie unchanged.
