Which statement best describes how water moves during osmosis across a selectively permeable membrane?

• A. Water moves only through phospholipids in the membrane and cannot pass through protein channels.
• B. Water moves from a region of lower solute concentration (higher water potential) to a region of higher solute concentration (lower water potential).
• C. Water moves from a region of higher solute concentration to a region of lower solute concentration until solute concentrations are equal.
• D. Water is actively pumped across the membrane against its concentration gradient using ATP.

Answer: (B)
