The relation between osmotic pressure (Π) and lowering of vapor pressure in an infinitely dilute solution is:

1. (a) \(\Pi = V^0 RT \ln\left(\frac{p}{p^0}\right)\)
2. (b) \(\Pi = \frac{RT}{V^0} \ln\left(\frac{p^0}{p}\right)\)
3. (c) \(\Pi = V^0 + RT \ln\left(\frac{p}{p^0}\right)\)
4. (d) \(\Pi = V^0 - RT \ln\left(\frac{p}{p^0}\right)\)
