Solution:
Option(D) is correct

The percentage increase in production compared to previous year for different years are:

$\begin{align*}
\text{In 1996,}\\ 
&=\left[\dfrac{40 - 25}{25} × 100\right]\%\\
&= 60\%.\\
\text{In 1997,}\\ 
&=\left[\dfrac{60 - 40}{40} × 100\right]\%\\
&= 50\%.
\end{align*}$

In 1998 there is a decrease in production.

$\begin{align*}
\text{In 1999,}\\
& =\left[\dfrac{65 - 45}{ 45} × 100\right]\%\\
& = 44.44\%
\end{align*}$

In 2000 there is a decrease in production.

$\begin{align*}
\text{In 2001,}\\
& =\left[\dfrac{75 - 50}{ 50} × 100\right]\%\\
& = 50\%.\\
\text{In 2002,}\\
& =\left[\dfrac{80 - 75}{ 75} × 100\right]\%\\
& = 6.67\%.
\end{align*}$

Clearly, there is maximum percentage increase in production in 1996
