c). water moves to an area of lower concentration between sugar molecules in the bottom of a beaker.
Explanation:
Osmosis is a process which solvent such as water in most of the cases, moves from its higher concentration to its lower concentration when two concentrations are separated by a semipermeable membrane or differentially permeable membrane.
As a result of osmosis, the concentration on both sides of a membrane becomes equal. In the option c) of the question sugar molecules in the beaker is not separated by a semipermeable membrane thus osmosis will not occur.
