Consider the Following Equation: GHG = × ×

Consider the following equation: GHG = × × 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 2011 and 2015,a period when GDP increased by 5% and Energy/GDP was constant.We can conclude that GHG/Energy over the same period

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