Answer: b. mind games and your money
Explanation:
This falls under Mental accounting where our minds play games with our money by dividing them into various accounts and uses based on our emotions.
Sunk costs play a big part in this because we get so attached to the accounts we have put a lot of effort in while neglecting those we have not or do not want to think about. Maria here is proud of her savings account so much so that she does not see the detrimental effect of not paying off the credit card debt which is rising rapidly.
Her savings account is now a sunk cost and she doesn't realize. This principle can help advise her so she understands the games her mind is playing on her and fix it before the damage gets worse.
