Economic considerations colour every aspect of international dealings, and nations are just like individuals in that the lender sets the terms of its dealings with the borrower. That is why a nation that owes money to another nation cannot be world leader.
The reasoning in the passage assumes which one of the following?
(A) A nation that does not lend to any other nation cannot be a world leader.
(B) A nation that can set the terms of its dealings with other nations is certain
to be a world leader.
(C) A nation that has the terms of its dealings with another action set by that
nation cannot be a world leader.
(D) A nation that is a world leader can borrow from another nation as long as that
other nation does not set the terms of the dealings between the two nations.
(E) A nation that has no dealings with any other nation cannot be world leader.

OA is C. I agree. However, I am not so sure how to eliminate choice D.
