Concept:Prime cost is the total of all direct costs incurred in production, which includes direct materials, direct labour, and direct expenses.
Explanation:Prime cost is calculated using the formula:
Prime Cost=Cost of Raw Materials Consumed+Direct Labour+Direct ExpensesFrom the list given, item i is the cost of raw materials consumed, which counts as direct materials.
Item iii is direct labour, which is a direct cost.
Item vi is direct expenses, which are also direct costs.
Items ii (indirect expenses), iv (factory expenses), and v (work-in-progress) are not part of prime cost because they are indirect costs or valuation items.
Hence, prime cost is obtained by adding i, iii, and vi only.
Answer:Option B: i, iii and vi.
