Answer:
Option C
Step-by-step explanation:
Whenever a large purchase is made, a person tries to pay a large part of it in the form of down payment so that his amount due reduces and thus he/she has to take a loan of lesser amount.
This shall reduce his monthly interest. In fact the higher is the down payment, the lower is the loan amount and hence the lower is the interest paid on it on monthly basis.
Thus, option C is correct
