Solution

C is correct. A company with consistent operating margins and a stable market share in a highly specialized business embarks on a significant and ambitious strategic change. Its success will depend entirely on how well management succeeds in delivering on its objective by improving margins (either by increasing prices or reducing costs) and taking market share from its competitors. Considering the relatively small size of the business, it may be difficult. Considering that many manufacturing businesses in the same industry typically operate around similar margins, any margin improvement may be difficult. That a manufacturer replaces aging factory machinery with similar but more efficient equipment is not an example of execution risk; it is part of regular improvement and capital investment. That a marketer of high-fashion pet accessories tests the market to see if there is demand for glamourous dog harnesses made with faux fur is a standard and common expansion of an existing product line with limited risk.
