Two mistakes in the questions: Coleman is world record holder since 2018, Su Bingtian has only the 5th time almost a 10th of a second behind; and the 4x100 world record is 36.84s and not as it says in the question.
6 is misleading. Su Bingtian has recorded the fastest 60m split ever (in a 100m race). But this is not a ‘world record’ by any standard definition. Rephrasing would make it quite a good question.
