Selling and administrative budget

Which of the following most accurately describes the selling and administrative (S&A) budget?

• AIt plans all manufacturing costs that cannot be traced to individual units, including variable and fixed factory overhead.
• BIt plans all non-manufacturing operating costs for the period — including variable selling costs and fixed administrative costs — and these are period costs charged directly to the income statement.
• CIt covers both factory overhead and head-office costs because both arise from running the wider organisation.
• DIt is prepared after the cash budget, because the timing of cash payments for administrative costs must be confirmed first.
