For many businesses, a major source of ________ comes from the sale of merchandise and productsa.ROIb.revenuec.goodwilld.profit

The correct answer to fill in the blank is b. revenue.

Explanation:

Revenue is the total income generated by the sale of goods or services in a business. It is a key indicator of business performance and is often the primary source of income for many companies. While ROI (Return on Investment), goodwill, and profit are important financial concepts, they do not represent the primary source of income generated from sales directly.

Thus, in the context of the statement, "For many businesses, a major source of revenue comes from the sale of merchandise and products," makes logical sense. Revenue directly correlates with sales performance in the business context.
