Final answer:
Carla is likely to get an unsecured loan if she has a high credit score or demonstrates a steady income over a long period.
Step-by-step explanation:
When applying for an unsecured loan, there are multiple conditions that can increase the likelihood of approval. Option 1, having a high credit score, is one of those conditions. A high credit score indicates that the borrower has a history of responsible borrowing and is more likely to repay the loan on time.
Option 2, pledging collateral of high value, is not related to an unsecured loan. In an unsecured loan, there is no collateral involved.
Option 3, demonstrating a steady income over a long period, can also increase the likelihood of approval for an unsecured loan. A steady income shows the ability to make regular loan repayments.
Option 4, applying for a small loan amount, may not necessarily impact the likelihood of approval for an unsecured loan, as the loan amount does not determine the loan's security.
