Well,

Homeostasis means "maintaining the status quo." That just means remaining the same.

The first, second, and fourth options, do not represent homeostasis, as something happens to the organism that is not normal.

The third example is an example of homeostasis because the cactus is preparing for the dry period, during which it can maintain the status quo because of its stored water.
