Answer:
B. The zero based budget requires managers to re-justify every planned expenditure every year.
Step-by-step explanation:
A zero based budget is one that does not take into account historical data when it is considering the present year budget. Each departmental requirement is re-evaluated and a new amount is assigned as budget for the year.
However conventional budgets carryover the previous year's expenses as a base data point. This results in similar budgeting across years.
So the main difference between the two is that zero based budget requires managers to re-justify every planned expenditure every year.
