Which of the following is sent as a reply to an inquiry?

Out of the given options, the response sent to an inquiry is a "Quotation". A quotation is a document that provides the price, terms, and conditions for goods or services that a company is willing to provide to a potential customer. It outlines the specific details of what is being offered, including the price and the quantity of the product or service. On the other hand, a "tender" is a formal offer made by a company to provide goods or services to another company or organization. A "statement" is a document that shows a summary of financial transactions or activities. An "estimate" is a rough calculation of the cost of a project or service. And an "advice note" is a document that informs a customer about the delivery of goods or services. Therefore, the best option to send as a response to an inquiry is a "quotation" because it provides a detailed breakdown of what is being offered, including the price and the terms of the agreement.
