Final answer:
Managers who perceive a lack of belief in the budget from top management are most likely to disengage and become inactive in the budgeting process.
Step-by-step explanation:
Managers who feel that top management does not believe in the budget are most likely to be inactive participants in the budgeting process. A lack of confidence in upper management's commitment to budgeting can lead to a lack of engagement and participation from managers. Without clear support and belief in the budget from the top, managers may feel that their efforts in the budgeting process are undervalued or likely to be ineffective. This situation could discourage active involvement and potentially lead to budgetary neglect or disinterest in seeking out feasible solutions or contributing to the budget process.
