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 decreased by 6% between 2012 and 2014,a period when GDP increased by 4% and Energy/GDP decreased by 2%.We can conclude that GHG over the same period
Energy

A) remains unchanged.
B) decreased by 8%.
C) decreased by 6%.
D) decreased by 4%.
E) increased by 4%.
