Step-by-step explanation:
The correct answer to the question "What is a small-scale business in which people work mostly at home?" is Cottage industry. A cottage industry is a small-scale business typically operated out of the home, where individuals or families produce goods or offer services.

While some cottage industries may grow to become larger enterprises, they often begin as non-employer businesses with income determined by products sold or services rendered, rather than a fixed salary.
