Crenation is the term for which change in red blood cells?

Explanation:
Crenation describes the shrinking of red blood cells when water leaves the cell in a hypertonic environment. The cell membrane pulls inward, giving the cell a crinkled, shriveled appearance. This crinkled, smaller form is what crenation refers to. Spreading of red blood cells isn’t a standard morphological change, normal-shaped cells are seen in isotonic conditions, and increased volume means swelling, not shrinking. So crenation best matches the crinkled/shriveled appearance.
