Final answer:
A prepaid card is the best option for Bella to manage her finances without the risk of going into debt, as it limits spending to the amount preloaded on the card.
Step-by-step explanation:
Bella is anxious about her financial management and the form of payment that may help her better manage her situation is a prepaid card (D). Unlike credit cards which allow for borrowing money that must be paid back later, potentially leading to debt, prepaid cards only permit spending the money that has been loaded onto them. This helps avoid debt because you cannot spend more than what is on the card. Moreover, a prepaid card differs from a debit card as it is not linked directly to a bank account but rather preloaded with funds. Unlike credit and debit cards, using a prepaid card means not having the possibility to spend more money than what has been stored on the card, ensuring Bella cannot go into debt.
