At 12 tons of potato production, Lerato's agribusiness firm has marginal revenue equals marginal cost. This is a point of_________ A. Collusion B. Profit maximization C. Market equilibrium D. Diminishing returns to scale

To answer the question step by step:

1. Identify the key terms: The key terms in the question are "marginal revenue," "marginal cost," and the options provided (A. Collusion, B. Profit maximization, C. Market equilibrium, D. Diminishing returns to scale).

2. Understand the economic concepts:

   • Marginal Revenue (MR): The additional revenue that one more unit of a product will bring.
   • Marginal Cost (MC): The additional cost of producing one more unit of a product.
   • Profit Maximization: This occurs when a firm's marginal revenue equals its marginal cost (MR = MC). At this point, the firm is making the most profit possible.
   • Collusion: An agreement between firms to limit competition and increase profits.
   • Market Equilibrium: The point where the quantity demanded equals the quantity supplied.
   • Diminishing Returns to Scale: A situation where increasing the amount of inputs results in a less than proportional increase in output.

3. Analyze the given information: The question states that at 12 tons of potato production, Lerato's agribusiness firm has marginal revenue equal to marginal cost.

4. Match the concept to the options:

   • Collusion: This is not related to MR = MC.
   • Profit maximization: This is directly related to MR = MC.
   • Market equilibrium: This is related to supply and demand, not MR = MC.
   • Diminishing returns to scale: This is related to production efficiency, not MR = MC.

5. Conclusion: The point where marginal revenue equals marginal cost is the point of profit maximization.

Therefore, the correct answer is B. Profit maximization.
