उत्तर : 1. "6 months"
व्याख्या :

Answer: A) 6 months Explanation: 6 months after graduating or quitting school when you have to start paying back the loans.   A grace period is one term that’s provided for student loans that allow you to delay payments up to a certain length of time, without penalty. During a grace period no late charges would apply, and the loan would not risk falling into default for missed payments. The grace period allows you time to find financial stability prior to having to make payments on your student loans.   Many students use student loans to help pay for their college expenses, including tuition, books, room and board, and other living expenses. Students are expected to repay these loans when they graduate.
