C) Master budgeting.
D) Activity-based budgeting.
E) Cash budgeting.

Activity-based budgeting is a budget system that is based on expected activities and their levels. It helps management to plan for the resources required to perform the activities. It is a more accurate and detailed budgeting method than traditional budgeting as it takes into account the activities that drive the costs, rather than simply using historical data. Master budgeting is a comprehensive budgeting approach that includes all of the budgets for an organization, including the operating budget, capital budget, and financial budget. Traditional budgeting is a budgeting method that uses historical data to estimate future expenses. Cash budgeting is a budgeting method that focuses on the organization's cash inflows and outflows. Management budgeting is a term that is sometimes used to describe the process of setting goals and objectives for an organization, rather than a specific budgeting method.
