A saturated solution of non-radioactive sugar was taken and a little radioactive sugar was added to it. A small amount of it gets dissolved in solution and an equal amount of sugar was precipitated. This proves

1. The equilibrium has not been established in the solution

2. Radioactive sugar can displace non-radioactive sugar from its solution.

3. Equilibrium is dynamic in nature

4. None of the above
