Which statement is true A. The cell membrane of the onion cell shrunk because they lost water
B. All of the above
C. Water molecules left the onion cells due to passive transport.
D. The solution has a higher concentration of salt and a lower concentration of water than the onion cell.

[Opt:- B] All the given statements are true.

Explanation:

So basically, the question is based on what will happen if we put an onion cell in salt water.

Since salt water is a hypertonic solution, exosmosis takes place. And as a result, the water molecules present inside the onion cell move outside the cell through passive transportation, which leads to shrinkage of the cell.
