Now according to option$\left( A \right)$ Paper$- 1$ is double thicker than paper$- 2$ but it clear visible that Paper$- 1$ is not double thicker than paper$- 2$.Thus, option $\left( A \right)$is incorrect.
Now according to option$\left( C \right)$ thickness of Paper$- 1$ is one fourth than paper$- 2$ but it is clearly visible that thickness of Paper$- 1$ is not one fourth than paper$- 2$ because the thickness of paper$- 1$ is $0.004m$ and the thickness of paper$- 2$ is $0.008m$ and $0.004$ is not one fourth of $0.008$ .Thus option $\left( C \right)$ is incorrect.
Now according to option $\left( D \right)$ paper$- 1$ and paper$- 2$ are both equally thick but it is clearly visible that they both are not equally thick. As, $0.004$ and $0.008$ are not equal. Thus the option $\left( D \right)$ is incorrect.
Now according to option $\left( B \right)$ thickness of Paper$- 1$ is half than paper$- 2$ and it is clearly visible that thickness of paper$- 1$ is half than paper$- 2$. As, $0.004$ is half of $0.008$. Thus the option $\left( B \right)$ is correct.
Hence, the correct option is $\left( B \right)$ .
