The correct answer is C) A feedback mechanism for maintaining homeostasis.

Guard cells in plant leaves play a crucial role in regulating the loss of water through transpiration. On hot and dry days, plants need to conserve water to prevent dehydration. The dying of guard cells is an example of a feedback mechanism for maintaining homeostasis in plants.

To get the answer to this question, you need to understand the role of guard cells in regulating water loss in plants. By closing their openings (known as stomata), which are made up of the guard cells, plants can minimize the transpiration rate and conserve water.

Therefore, the dying of guard cells in response to hot dry days is an adaptive response to the environmental conditions. This feedback mechanism helps plants maintain homeostasis by conserving water when it is needed.
