when placed in water, wilted plants lose their limpness because of
active transport of salts into the plant cells.
active transport of salts out of the plant cells.
osmosis of water out of the plant cells.
osmosis of water into the plant cells.

Explanation:

Wilted plants have cells with low water content, making their cytoplasm and vacuoles shrunken. When placed in water, the outside environment has a higher water potential than the plant cells. Osmosis is the passive movement of water from an area of higher water potential to lower water potential across a semipermeable membrane. Water moves into the plant cells via osmosis, causing the cells to become turgid, which eliminates the limpness. Active transport of salts is not the direct cause of the immediate reversal of wilting here, and water moving out would worsen wilting.

Answer:

osmosis of water into the plant cells.
