Sort customer satisfaction scores into Promoter, Passive and Detractor with IFS

IFS checks its conditions in order and stops at the first one that holds, which is exactly the behavior three score bands need, and it reads as a flat list instead of a staircase of nested IFs.

Task:

You run customer experience reporting for a software company's support line. After every call, the customer rates the interaction from 0 to 10, and reporting sorts each response into an NPS band: 9 or 10 is a Promoter, 7 or 8 is a Passive, and 6 or below is a Detractor. In column C, classify each score from C2 to C7.
