Answer:
b. He has five credits cards with high balances.
Step-by-step explanation:
A VantageScore is a credit score model that shows the probability that someone will pay the loans. A 400 VantageScore is very poor and people can get this score for different situations like bankruptcies as they will appear in your report for up to 10 years, having high utilization rates on your credit card and missing payments. According to this, the answer is that the factor that could be the cause is: he has five credits cards with high balances because he would have a high utilization rate which hurts the credit score.
The other options are not right because a bankruptcy appears in the report for up to 10 years, a low debt to credit ratio shows that you use your credit in a responsible form and it won't hurt your credit acore. Also, if someone doesn't have a credit history, there is no score because there is no data to define that.
