Answer:
The correct option is D = regionNumber
Explanation:
In this scenario we want to know customers who owe more than $1000 each, in each of 12 sales regions. And the customer data variables include name, zip-code, balanceDue and regionNumber; based on the customer data variables names and zip-code will not really affect our output. It is based on balanceDue that we increment the number of customer owing in a particular region (regionNumber).
Therefore, we would add 1 to an array element whose subscript would be represented by regionNumber since we are interested to know the number of customer owing in each of the 12 sales regions.
