The correct option is 2 only because a "vote-on-account" allows the government to obtain approval for essential expenditures to continue functioning until the full budget is presented, thereby focusing primarily on expenditure without addressing revenue collection. In contrast, an "interim budget," typically presented by a caretaker government, includes both expenditure and revenue estimates, as it aims to provide a complete financial framework for a transitional period before general elections. This distinction is crucial for understanding financial governance in different political contexts, as explored in UPSC materials on budgeting and economic policy.
