The correct answer is:
$\rho_1 < \rho_3 < \rho_2$
$\rho_1 < \rho_3 < \rho_2$
As liquid 1 floats above liquid 2 ,
$$
\rho_1 < \rho_2
$$
The ball is unable to sink into liquid 2 ,
$\rho_3 < \rho_2$ The ball is unable to rise over liquid 1 ,
$\begin{array}{ll} & \rho_1 < \rho_3 \\ \text { Thus, } & \rho_1 < \rho_3 < \rho_2\end{array}$
$$
\rho_1 < \rho_2
$$
The ball is unable to sink into liquid 2 ,
$\rho_3 < \rho_2$ The ball is unable to rise over liquid 1 ,
$\begin{array}{ll} & \rho_1 < \rho_3 \\ \text { Thus, } & \rho_1 < \rho_3 < \rho_2\end{array}$
