The action that will increase your debt the most over a year is "Paying just the minimum payment for credit cards each month". Here's why:

1. Paying off your entire credit card bill once a year: This would not increase your debt significantly over the year, especially if you pay off the entire balance. You might incur some interest charges if you carry a balance throughout the year, but it would be less than if you only made minimum payments.

2. Applying for multiple credit cards in a year: While this could potentially increase your debt if you use all the credit cards and don't pay off the balances, it's not guaranteed to do so. It depends on how you use the cards.

3. Paying just the minimum payment for credit cards each month: This is the action that will increase your debt the most. When you only make the minimum payment, the rest of your balance accrues interest. This means you're not only paying off the original amount you spent, but also the interest that has accumulated on that amount. Over time, this can lead to a significant increase in your debt.

4. Using credit cards as sources of cash once a year: This could increase your debt, especially if you don't pay off the cash advance quickly. Cash advances often have higher interest rates than regular purchases, and there's usually no grace period, so interest starts accruing immediately. However, if it's only done once a year and paid off quickly, it wouldn't increase your debt as much as only making minimum payments each month.
