Just by observation, you can be sure that 2008 can be eliminated. Now among 2010 and 2011, the ‘Equity’ part is same for both of them. To have a higher ratio value, the ‘commodity’ part should be higher and ‘Fixed Income’ part should be lower. Thus among these two years, we can again eliminate 2011. The following table will give you the approximate value for years 2009 & 2010.

$\begin{array}{cccc}Year& Commodity& FixedIncome& Ratio\\ 2009& 0.04& 0.20& 0.20\\ 2010& 0.02& 0.16& 0.125\end{array}$
We can see that the ‘commodity’ for 2010 is almost double that of ‘2009’ whereas the ‘fixed income’ part doesn’t have that much variation. Thus 2009 is the answer.
