Answer:
c. flexible-price
Explanation:
A flexible pricing policy provides room for the business and the customer to negotiate for the final price of a product. In other words, the price indicated on the item is not fixed. The seller and buyer can agree to alter it either upwards or downwards.
A flexible pricing strategy enables a business to adjust its prices to suit the market demand. It will allow a company to counter low prices by competitors in cases of price wars. In some instances, businesses set slightly high prices to provide for negotiations. Flexible pricing is common, especially in tailor-made products.
