Final Answer : A, Explanation :  To maximize profit, a firm in a perfectly competitive market hires workers up to the point where the value of the marginal product of labor (VMPL) equals the wage rate. VMPL is calculated as the marginal product of labor (the additional output produced by an additional worker) multiplied by the price of the product. Without the specific numbers from the table, the general principle is that if hiring 4 workers results in a VMPL higher than $40, the firm can increase profit by hiring more workers until VMPL equals the wage rate. Since the correct answer is to hire 1 more worker, it implies that the VMPL for the 5th worker is at least $40, matching the wage rate, thus maximizing profit.
