Correct option is D
The correct answer is (d) the ratio between export prices and import prices.
The term "terms of trade" refers to the ratio between the prices at which a country sells its exports and the prices paid for its imports.
It is an important indicator of the economic health of a country, reflecting the relative value of its exports compared to its imports.
An improvement in the terms of trade means that a country can buy more imports for any given level of exports, indicating stronger economic power and vice versa.
