An object is fully submerged in a liquid. A student determines the ratio $\dfrac{\text{upthrust acting on the object}}{\text{weight of the object}}$. Which single change would double the value of this ratio?

1. AUse a different liquid that has twice the density and the same volume as the original liquid.
2. BUse a different object that has half the volume and the same density as the original object.
3. CUse a different object that has twice the density and the same volume as the original object.
4. DUse a different object that has twice the volume and the same density as the original object.
