Final answer:
Production supplies are unlikely to be classified as a fixed cost because they vary with the level of production, unlike fixed costs such as property taxes, legal department salaries, and leased equipment costs. Correct option is b.
Step-by-step explanation:
Out of the options provided, production supplies are unlikely to be classified as a fixed cost with respect to the number of units produced and sold.
Unlike property taxes on a headquarters building, legal department salaries, and the cost of leasing the company's mainframe computer, the cost of production supplies tends to vary with the level of production. Such costs fall into the category of variable costs, as they increase with an increase in production and decrease when production levels are reduced.
Fixed costs are expenditures that do not change regardless of the level of production, such as rent on a factory, or research and development costs. In contrast, variable costs fluctuate according to production output. Therefore, production supplies don't fit the fixed cost definition since they directly depend on the quantity of product being created.
