B. By producing fewer units that require a lot of direct labor, less of the overhead will be allocated to units that are in inventory at the end of the period because there will be fewer units in inventory. This will mean that less of the overhead is on the balance sheet and more is on the income statement, reducing net income.

C. By deferring expenses, the income in the current period will be higher, giving a bigger bonus.

D. By increasing production schedules independent of customer demand, more units will be in inventory at the end of the year, meaning that more fixed costs will be on the balance sheet and not on the income statement. This will increase income.
