Answer:
D. Budget
Step-by-step explanation:
Pat has Been riding informal proposals for more than 20 years. Pat feels that many people forget the call for action and present the reader with the offer prior to signing a binding contract.
This offer prior to signing a binding contract is a form of background work not an introduction neither is it request for authorization or budget.
It's not in the protocol of contract signing but it's a special way to have your contract signed.
