Which factors are known to influence credit scores?

Credit scores are influenced by a variety of factors that lenders consider when evaluating an individual's creditworthiness. The length of credit history is critical because it reflects how long a person has been using credit, which can indicate their experience and reliability in managing debt. A longer credit history generally contributes positively to a credit score as it provides more data on repayment habits.

Additionally, when it comes to types of credit used, having a mixture of credit accounts—such as revolving credit (credit cards) and installment loans (car loans, mortgages)—can positively affect a credit score. This diversity shows lenders that the borrower can handle various forms of credit responsibly. Likewise, new credit inquiries, which occur when a consumer applies for credit, can temporarily lower a credit score, as numerous inquiries may signal financial distress or higher risk to lenders.

The combination of both the length of credit history and the types of credit used plays a significant role in determining a credit score, making the option that includes both these factors correct. Therefore, recognizing that both the length of credit history and types of credit significantly impact credit scores explains why the selected answer is accurate.
