Suggested Answer: B

We need one reference data input for LocationIncomes, which rarely changes.

We need two queries, on for in-store customers, and one for online customers.

For each query two outputs is needed.

Note: Stream Analytics also supports input known as reference data. Reference data is either completely static or changes slowly.
