How to match a name to a value ?

Hi guys
I need a formula to perform a very specific action.As you can see in the image uploaded,I've written IDes in C column and amount of their debts in front of them which are in column D.In column I12 I have asked the program to select the highest amount of debt among all.Here is the problem,I can not ask Excel to write the owner of debt next to it (I12).But as you can see,I manually wrote.
Thank you for taking time.
and with thanking Forum Moderator here is the xlsx link added.
