If you're writing an unsolicited proposal,you won't need to

A) convince readers that a problem or opportunity exists.
B) prove that you can solve the problem or opportunity.
C) explain why readers should take action.
D) follow every detail of the request-for-proposals format.
E) establish your qualifications in solving the problem.

Unsolicited proposals are not bound by the request-for-proposals format, so option D is correct. However, convincing readers of the problem or opportunity, proving that you can solve the problem or opportunity, explaining why readers should take action, and establishing your qualifications in solving the problem are still important components of an unsolicited proposal.
