Which of the following types of proposals are generally prepared at the request of an external
Party that requires a product or service?

A) Grant
B) Solicited
C) Unsolicited
D) Sales
E) Internal

A solicited proposal is prepared in response to a request from an external party who requires a product or service. This request can come in the form of a solicitation, such as a request for proposal (RFP) or a request for quotation (RFQ). The other options do not necessarily require an external party to request the proposal. A grant proposal is typically submitted to a funding agency, an unsolicited proposal is initiated by the proposal writer without an invitation, a sales proposal is initiated by a seller to solicit business, and an internal proposal is prepared within an organization to address an internal issue.
