To separate a solid substance that has dissolved in water, the correct method would be:

A. Boil the water away, leaving the substance behind in the beaker.

When a solid dissolves in water, it forms a solution, and boiling the water will cause it to evaporate, leaving the dissolved substance behind if it's a non-volatile solid. The other options are not suitable for separating a dissolved solid from a liquid.
