Final answer:
Cotton-soft Facial Tissues would be considered a Cash Cow on the BCG matrix because it has a high market share in a declining growth industry, providing steady revenue with low investment.
Step-by-step explanation:
If Cotton-soft Facial Tissues has the largest market share but is in a declining growth industry, according to the BCG (Boston Consulting Group) matrix, the company would fall into the Cash Cow category. This is because Cash Cows are characterized by a high market share in a slow-growing industry. These businesses are usually mature and established, and they have the potential to generate a steady stream of revenue with relatively low investment. Although the growth prospects are limited, Cash Cows can provide the capital needed to fund other business units within an organization, like Stars or Question Marks.
