निम्नलिखित में से कौन सा गणितीय समीकरण 'लक्षित लागत' (Target Cost) को सही ढंग से दर्शाता है?

Up to a given level of activity in each period, the purchase price per unit of a raw material is constant. Beyond that point, a lower price per unit applies to further units purchased and also retrospectively to all units already purchased. Which type of cost behavior pattern does this represent on a total cost graph?

Techno-Flow Ltd has total overheads of 2,000,000 (Setup: 500,000; Quality Inspection: 300,000; Machining: 1,200,000). The company produces two models: 1. Standard: 100 batches, 10,000 machine hours, 50 inspections, 30,000 direct labor hours. 2. Premium: 400 batches, 15,000 machine hours, 250 inspections, 20,000 direct labor hours (Total units produced = 40,000 units). Evaluate the following analytical findings: Statement A: Traditional allocation via direct labor hours yields a rate of 40/hr, assigning 800,000 to Premium (20.00/unit). Statement B: Activity Based Costing (ABC) computes a setup rate of 1,000/batch, inspection rate of 1,000/inspection, and machining rate of 48/hour, yielding a Premium overhead of 1,370,000 (34.25/unit). Statement C: Traditional costing distorts product costs by underpricing the Premium model's overhead by 14.25/unit. Statement D: Machine hours are the primary driver of setup costs in ABC systems. Which of the combinations correctly evaluates these findings?
