During an expedition across the subterranean caverns of a remote moon, an astro-chemist accidentally dissolves a specimen of rare luminescent mineral crystals into a flask of pure water, forming a clear, uniform solution. Because the mission requires the recovery of the dry mineral crystals to analyze their solid lattice structure, the liquid solvent must be completely removed without losing the non-volatile solute. Which separation technique should the researcher carry out to collect the dry solid mineral from this liquid mixture?

A) Passing the liquid through an ultra-fine porous filter membrane

B) Heating the solution to drive off the liquid water by evaporation

C) Spinning the flask at high rotational speed in a centrifuge

D) Applying an external magnetic field to extract the dissolved ions
