项目经理正在规划一个有多个工作包的项目。每个工作包都有自己定义的范围，但资金将在项目层面。项目经理应该如何确定分配的资源预算是否足以覆盖项目的资源成本？
A project manager is planning a project with multiple work packages.  Each work package has its own defined scope, but funding will be at the project level.  How should the project manager determine if the allocated resource budget is sufficient to cover the resource costs of the project?

A.将分配的预算除以工作包的数量，验证每个工作包可以在分配的预算内完成。 Divide the allocated budget by the number of work packages and verify that each work package can be completed within the allocated budget.

B.估计工作包一级的费用，并将这些费用相加，以计算项目的总费用，并与已分配的预算进行比较。 Estimate the costs at the work package level and add those costs to calculate the total cost of the project and compare it to the allocated budget.

C.创建预算燃耗和范围燃耗，并在分配的预算耗尽之前验证项目范围已完成。 Create a budget burn down and a scope burn up and then verify that the project scope is completed before the allocated budget is depleted

D.按其重要性顺序为每个工作包提供资金，并将任何剩余范围从无资金资助的工作包转移到有资金资助的工作包。 Fund each work package in the order of its importance and shift any remaining scope from non-funded work packages to funded work packages.
