Define "entrepreneurship."

Entrepreneurship is best defined as the process of starting and running one's own business in order to make a profit. This definition encompasses the wide range of activities involved in identifying market opportunities, creating a business concept, financing the venture, managing operations, and ultimately driving the enterprise toward profitability. Entrepreneurs take on the risks associated with launching new business ventures, and their innovative ideas and willingness to navigate unpredictable challenges are pivotal in stimulating economic growth and job creation.

While other options touch on aspects of business and investment, they do not capture the comprehensive nature of entrepreneurship. Investing in stocks and bonds relates more to financial markets than to the act of creating a business. Management of existing businesses focuses solely on operational aspects without considering the entrepreneurial spirit of starting something new. Lastly, donating to startups without expecting a return is philanthropic in nature and does not reflect the profit-driven goals of entrepreneurship. Hence, option B encapsulates the essence of what it means to be an entrepreneur.
