Final answer:
The best type of loan for Colette to consolidate her credit card debt is a Consolidation loan, as it is specifically designed to roll multiple debts into one with potentially lower interest rates.
Step-by-step explanation:
For Colette, who wants to consolidate her credit card debt, the best type of loan to inquire about is a Consolidation loan (A). This specific type of loan is designed to combine multiple debts, particularly those from credit cards, into a single loan with a potentially lower interest rate. It simplifies the repayment process because it involves making a single monthly payment rather than juggling several payments with varying interest rates. Other types of loans, such as a Mortgage (B), Personal loan (C), and Student loan (D), are usually for specific purposes like home buying, personal expenses, or education, and therefore not ideal for debt consolidation.
