To calculate real GDP, we need to use constant prices of the base year, in this case, 2003.

Real GDP in 2003 = (100 x $500) + (50 x $800) = $75,000
Real GDP in 2009 = (200 x $700) + (100 x $1200) = $260,000

Therefore, the growth in real GDP = (Real GDP in 2009 - Real GDP in 2003) / Real GDP in 2003 x 100

= ($260,000 - $75,000) / $75,000 x 100 = 246.67%

The growth in real GDP is 246.67%, but this is not one of the answer choices. However, we can see that option C, which is 83%, is the closest to the actual value of the growth rate. Therefore, the best choice is C.
