The correct answer is: Only (i) and (ii).
Cost-plus pricing is a pricing method in which a company sets its prices based on the costs of production plus a profit margin. This method is often used by companies that produce customized products or services, as it allows them to recover their costs and make a profit.
Public utility pricing is a pricing method used by public utilities, such as electricity companies, water companies, and gas companies. This method sets prices based on the costs of production plus a fair return on investment. The goal of public utility pricing is to ensure that consumers have access to essential services at a fair price.
Refusal pricing is a pricing method in which a company sets its prices so high that it discourages customers from buying its products or services. This method is often used by companies that have a monopoly on a particular product or service.
Monopoly pricing is a pricing method in which a company sets its prices without regard to the costs of production or the prices of competing products. This method is often used by companies that have a monopoly on a particular product or service.
In conclusion, cost-plus pricing is considered appropriate for product tailoring and public utility pricing. It is not considered appropriate for refusal pricing or monopoly pricing.
