Answer
Answer (as printed): D

Average production (in 10000 tonnes) over the given years $$\begin{aligned} & =\frac{(25+40+60+45+65+50+75+80)}{8} \\ & =\frac{440}{8}=55 . \end{aligned}$$ Clearly, the productions during 2007, 2009, 2011 and 2012 are more than the average production. These are 4 years.
