In how many of the given years were the exports more than the imports?

Answer: Option D

Clearly, Export > Import only when $$\frac{\text{Import}}{\text{Export}}$$   < 1.
From the graph it is clear that the above ratio is less than 1 in the years 2005, 2006, 2007 and 2010.
Thus (Imports : Exports) < 1 in 4 years
