As $Y=(\large\frac{F}{a})\frac{l}{\Delta l}$

$\Rightarrow F=\large\frac{Y\times a\times \Delta l}{l}$

$\Rightarrow \large\frac{2\times 106{11}\times \pi\times (2\times 10^{-3})^2\times 1\times 10^{-3}}{2}$

$\Rightarrow 4\pi\times 10^2$

$\Rightarrow 12.56\times 10^2N$

Hence (C) is the correct answer.
