Components of Production Overheads Steps:

• Recall production overheads include all indirect manufacturing costs like supervision, maintenance, and utilities, excluding only direct materials.
• Identify direct labor costs: wages of factory and assembly workers directly traceable to production.
• Note that budgeted production overheads often encompass total factory costs for allocation purposes, including direct labor in some integrated calculations.
• Evaluate options for completeness: select the one listing all factory-related wages and indirect expenses.

Why D is correct:

• It fully captures total production overheads by including both direct labor wages (factory and assembly) and indirect costs (supervisors' salaries, maintenance, cleaning materials), aligning with comprehensive budgeting under absorption costing principles.

Why the others are wrong:

• A omits indirect costs like supervision and maintenance, understating overheads.
• B excludes factory workers' wages and all indirect costs, incomplete for total overheads.
• C misses factory workers' wages, failing to include all direct labor components.

Final answer: D
