All businesses are involved in which types of activity?

The correct answer highlights the three essential types of activities that every business engages in: operating, investing, and financing.

Operating activities encompass the day-to-day functions necessary for a business to generate revenue. This includes selling goods and services, managing inventory, and handling customer services. Investing activities involve the acquisition and disposal of long-term assets, such as property, equipment, and investments in other businesses. These activities are crucial for the growth and sustainability of a business, as they set the foundation for future earnings and expansion. Financing activities, on the other hand, pertain to how a business funds its operations and growth, which includes obtaining loans, issuing stock, or paying dividends. These activities shape the financial structure and capacity of a business to operate and expand.

While sales and marketing, research and development, and human resources management are important functions within many businesses, they do not universally apply to all types of businesses across various industries. Operating, investing, and financing make up the core of all business activities, which is why this answer is the most comprehensive and universally applicable.
