Consider the Following Equation: GHG = GHG × Energy ×

Consider the following equation: GHG = GHG × Energy × GDP,
Energy GDP
Where GHG = world annual emissions of greenhouse gases Energy = world annual amount of energy consumed GDP = world's annual gross domestic product
Suppose GHG emissions increased by 10% between 2009 and 2013,a period when GDP increased by 5% and Energy/GDP was constant.We can conclude that GHG/Energy over the same period

A) decreased by 5%.
B) increased by 10%.
C) increased by 5%.
D) decreased by 10%.
E) was unchanged.
