Which Scenario Is an Example of a Beneficial Use of Credit

Which scenario is an example of a beneficial use of credit?

A) David uses his credit card to pay for furniture for his new home, and he pays the minimum monthly balance each month, taking several years to pay for the furniture plus interest.
B) Lily uses her credit card to pay rent on her apartment and pays as much of it off each month as she can afford. Although she pays more than the minimum payment, she isn't paying it in full, so even after she moves out, she will still be making payments on the apartment.
C) Olivia uses her credit card to buy a new car, so she can pay for it over the course of several years. Even after the car depreciates in value, she can still continue to pay it off.
D) Paula buys a condo for $200,000 and lives in it for 10 years, paying monthly mortgage payments that are slightly less than the average monthly rent in the area. After 10 years, she is able to sell the condo for $300,000 because the building has appreciated in value.
E) Justin takes an 8 percent fixed-rate mortgage to purchase his first home. He has trouble making the monthly payments, so he eventually sells the house for enough money to pay back the mortgage without making a profit or suffering a loss.
