Which of the following is sent in reply to a letter of enquiry?

A quotation is sent in reply to a letter of enquiry. When a potential customer sends a letter of enquiry requesting information about the price, quality, or availability of goods or services, the supplier usually responds with a quotation. A quotation is a formal statement of the supplier's offer to supply the requested goods or services at a specific price, usually valid for a limited time period. It includes the quantity, description, and unit price of the goods or services, as well as any other terms and conditions of the offer. The potential customer can then decide whether or not to accept the offer and place an order.
