At a given place where acceleration due to gravity is $g \ m/s^2$,a sphere of lead of density $d \ kg/m^3$ is gently released in a column of liquid of density $\rho \ kg/m^3$. If $d > \rho$,the sphere will:

• A
  Fall vertically with an acceleration $g \ m/s^2$
• B
  Fall vertically with no acceleration
• C
  Fall vertically with an acceleration $g \left( \frac{d - \rho}{d} \right)$
• D
  Fall vertically with an acceleration $g \left( \frac{\rho}{d} \right)$
