Statement:  Is buying things on installments to the customer ?

Arguments:

A. Only argument I is strong.
B. Only argument II is strong.
C. Either I or II is strong.
D. Neither I nor II is strong.
E. Both I and II are strong.

Answer: Option D

Explanation:

In buying things on installments, a customer has to pay more as the interest is also included. So, argument I does not hold.
