Two objects P and Q are put into a beaker of liquid. Object P stays afloat in the liquid, while object Q goes to the bottom. Which row could show the densities of object P, object Q and the liquid?
- Adensity of object P $= 1.2\ \text{g cm}^{-3}$, density of object Q $= 0.6\ \text{g cm}^{-3}$, density of liquid $= 0.8\ \text{g cm}^{-3}$
- Bdensity of object P $= 1.2\ \text{g cm}^{-3}$, density of object Q $= 1.4\ \text{g cm}^{-3}$, density of liquid $= 1.0\ \text{g cm}^{-3}$
- Cdensity of object P $= 11.3\ \text{g cm}^{-3}$, density of object Q $= 8.9\ \text{g cm}^{-3}$, density of liquid $= 13.6\ \text{g cm}^{-3}$
- Ddensity of object P $= 11.3\ \text{g cm}^{-3}$, density of object Q $= 19.3\ \text{g cm}^{-3}$, density of liquid $= 13.6\ \text{g cm}^{-3}$
