The correct answer is A. Actual.
When creating a budget, it's essential to track both your budgeted expenses (the amounts you plan to spend) and your actual expenses (the amounts you actually spend). This allows you to see if you're sticking to your budget and to identify any areas where you may need to adjust your spending. Tracking actual expenses is crucial for understanding your financial situation and making informed decisions for future budgeting. The other options, "Potential" and "Likely," do not fit the context of expense tracking in budgeting.
