Answer :
Molecules of a sugar sample behave when the sample dissolves in water the solute molecules separate from each other by dispersion. Option B.
Sucrose is a polar molecule. Polar water molecules attract the negative and positive regions of polar sucrose molecules, causing sucrose to dissolve in water. Sugar is a covalent, slightly polar compound that can dissolve in water due to its polarity.
Every time you break down a covalent compound like sugar you see a physical change. The molecules move further apart in the solvent but do not change. Dissolving sugar in water is a physical change. This is because no new matter is formed. Also, the process is reversible. Water and sugar are separated by evaporation followed by condensation and crystallization.
