A student loan is money a person borrows in order to:A.purchase a new house.B.buy luxury goods.C.pay off existing debt.D.pay for college tuition.

The correct answer is D. pay for college tuition.

Student loans are specifically designed to help individuals finance their education-related expenses. This includes tuition fees, textbooks, materials, and sometimes even living expenses while attending college or university. Unlike loans for purchasing a house or luxury goods, which serve different purposes, student loans are tailored to assist students in acquiring the financial means to pursue higher education.

While options A, B, and C refer to other financial goals, they do not align with the primary purpose of student loans. It is crucial for students to understand the terms and conditions of these loans, as they often come with interest rates and repayment plans that can significantly impact their finances after graduation.
