The correct Answer is:
**Step-by-Step Solution:** 1. **Definition of Homeostasis**: Homeostasis refers to the ability of an organism to maintain a stable internal environment despite changes in external conditions. This includes the regulation of various internal conditions such as temperature, pH, and osmotic pressure. 2. **Key Features of Homeostasis**: The main features of homeostasis include: - **Thermoregulation**: This is the process by which organisms maintain their body temperature within a certain range, regardless of external temperatures. - **Osmoregulation**: This involves the regulation of water and solute concentrations in the body to maintain osmotic balance. 3. **Evaluating Options**: - **Option A**: "Tendency to change with change in environment" - This is incorrect as homeostasis is about maintaining constant internal conditions. - **Option B**: "Tendency to resist change self-regulatory mechanism" - This is correct as homeostasis involves mechanisms that resist changes in the internal environment. - **Option C**: "Disturbance in regulatory control" - This is incorrect as it suggests a failure of homeostasis rather than its definition. - **Option D**: "Plants and animals extract used in homeopathy" - This is irrelevant to the concept of homeostasis. 4. **Conclusion**: The correct understanding of homeostasis is that it is a self-regulatory mechanism that allows organisms to resist changes in their internal environment, maintaining stability despite external fluctuations.
