The correct answer is option C. the movement of water from the central vacuoles of the cells into the solution.

Explanation:

In the given question onion cell was initially in 1% NaCl solution later student increase the concentration of the NaCl in the solution which makes the solution hypertonic.

A hypertonic cell is a solution with less water or more solute. Increasing salt concentration makes solute concentration high than inside the cell. Cell shrink in this case due to the osmosis or water movement from the high concentration region of water to the low concentration of water region.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
