Solution:
Option(B) is correct

The percentage change (rise/fall) in production from 2000 to 2001 for various models is:

For, 

\begin{align*}
P &=\left[\dfrac{176000 - 105000}{105000} × 100\right]\% \\
&= 67.62\% \text{, rise.}\\
Q &=\left[\dfrac{88000 - 52500}{52500} × 100\right]\% \\
&= 67.62\% \text{, rise.} \\
R &=\left[\dfrac{70000 - 66000}{70000} × 100\right]\% \\
&= 5.71\% \text{, fall.} \\
S &=\left[\dfrac{44000 - 35000}{35000} × 100\right]\% \\
&= 25.71\% \text{, rise.} \\
T &=\left[\dfrac{52500 - 44000}{52500} × 100\right]\% \\
&= 16.19\% \text{, fall.} \\
U &=\left[\dfrac{35000 - 22000}{35000} × 100\right]\% \\
&= 37.14\% \text{, fall.}
\end{align*}

Minimum percentage rise/fall is production is the case of model R
