After cutting cucumber, if salt is added, then water comes out due to

Correct answer: (c) Osmosis

Explanation

Osmosis is the movement of water (solvent) across a semi-permeable membrane from low to high solute concentration.

Salt makes the outside hypertonic, so water exits the cucumber cells to balance concentration.

Diffusion moves any solute particles; active transport needs cellular energy; passive transport moves solutes without energy.
