A sole enterprise is a business that is owned and operated by a single individual. It may flourish best in a retailing business because it typically involves a small-scale operation that can be easily managed by a single individual. In contrast, businesses such as mining, oil exploration, and car assembly require substantial investment, equipment, and technical expertise, which may be difficult for a sole proprietor to manage alone. A retail business, on the other hand, can be started with relatively low capital investment and can be managed effectively by a single individual with appropriate business skills. Therefore, a retail business is most suitable for a sole proprietorship.
