An object of weight W is suspended from a newton meter. When the object is completely immersed in water, the newton meter reads P. When the object is completely immersed in oil, the newton meter reads Q. What is the ratio $\dfrac{\text{density of oil}}{\text{density of water}}$?

1. A$\dfrac{W-P}{Q-P}$
2. B$\dfrac{Q-P}{W-P}$
3. C$\dfrac{W-P}{W-Q}$
4. D$\dfrac{W-Q}{W-P}$
