A financial plan of action expressed in monetary terms is known as

Several public-finance terms describe how money is planned, released, or held for government or organisational spending, and it is important to distinguish them from one another.

A budget is a financial plan of action, expressed in monetary terms, that sets out expected income and planned expenditure for a future period, usually a financial year. It is the master document from which spending authority is derived. A warrant is an authorisation, issued after the budget is approved, permitting a specific amount to actually be spent or withdrawn from public funds; it releases money rather than planning it. The consolidated fund is the main account into which government revenues are paid and from which authorised expenditure is drawn, it is a fund, not a plan. Imprest is a fixed sum of cash advanced to an officer for minor, day-to-day expenses, to be accounted for and replenished periodically; it is a method of controlling petty spending, not a plan expressed for the whole organisation.

Because it is the document that sets out a plan of action in monetary terms before any spending happens, the correct description is a budget.

Examination tip: a budget plans spending in advance, while a warrant authorises money to actually be released against that plan; do not confuse the planning stage with the release stage.
