The correct answer is C. Estimated selling price.
A tender price is the price that a company offers to sell a product or service to a potential customer. It is usually based on the company’s estimated costs of production, as well as its desired profit margin. The tender price is often used as a basis for negotiation between the company and the customer.
Option A, total production cost, is not correct because the tender price is not necessarily the same as the total production cost. The tender price may be higher or lower than the total production cost, depending on the company’s desired profit margin.
Option B, sales cost, is not correct because the tender price is not necessarily the same as the sales cost. The sales cost includes the cost of goods sold, as well as the costs of marketing and sales. The tender price may be higher or lower than the sales cost, depending on the company’s desired profit margin.
Option D, cost sheet of last period, is not correct because the tender price is not necessarily the same as the cost sheet of last period. The cost sheet of last period is a historical document that shows the costs of production for the previous period. The tender price is a forward-looking document that shows the estimated costs of production for the current or future period.
In conclusion, the correct answer is C. Estimated selling price.
