Explanation
An Advertisement Inviting Tender is option A: An Invitation for Proposal.
An advertisement inviting tender is a formal public announcement made by an organization or government agency to invite bids or proposals from interested parties to perform a particular job or provide a specific service. The advertisement usually provides details of the required job or service, the eligibility criteria, and the submission process for the proposals. The aim is to attract competitive offers from interested parties and ultimately select the best offer or proposal based on the evaluation criteria mentioned in the tender advertisement.
In this process, the organization or agency inviting tenders is not making an offer, rather it is inviting proposals or bids from interested parties to provide a specific product or service. The advertisement is an invitation to propose, and not an acceptance of any offer.
