To answer your question, "a dollar down and a dollar forever" represents a form of credit called the Installment Plan.
The quote "A dollar down and a dollar forever" describes buying goods on an installment plan. Option C is correct.
Installment plan refers to a system for paying for an item in fixed amounts at specified intervals.
This system enabled people to purchase goods over an extended period of time without having to put down much money at the moment of purchasing. In other words, the buyer pays part of the cost immediately and then makes small regular payments until the debt is completely paid.
