Which are the four main business functions?

• A. Operations, Marketing, Finance, Human Resources
• B. Production, Sales, Logistics, IT
• C. Research, Development, Marketing, Support
• D. Accounting, Legal, Compliance, Governance

Answer: (A)

Think of a business as a system that creates value by combining four broad activities. First, operations handles turning inputs like materials and labor into the finished goods or services the business offers. Second, marketing focuses on understanding customer needs, creating demand, and communicating the value of what’s offered. Third, finance takes care of money—planning, funding, budgeting, and tracking financial performance to keep the business solvent and able to grow. Fourth, human resources manages people—recruiting, training, developing talent, and shaping the organizational culture.

This set is the best answer because it captures the essential, ongoing functions that enable a business to produce, reach customers, stay financially healthy, and maintain its workforce. The other options mix activities that are either parts of these functions or represent specialized support or governance areas rather than the main value-creating blocks.
