Homeostasis: It is defined as the tendency of organisms to auto-regulate and maintains their internal environment in a stable state. The stable conditions include body temperature, fluid balance, PH of extracellular fluid, the concentration of sodium, potassium and calcium ions as well as that of blood sugar level. These activities are regulated in response to the changes in the external environmental conditions.
Thus, the option (a) is incorrect.
Natural selection is the process by which organisms with certain characteristics that help them survive and reproduce better are seen in greater numbers in future generations. Selection always acts group of individual or population doesn't act on a single individual.
Thus, the option (b) is incorrect.
Extinction is when all the members of a species die off. Extinction is caused by several factors such as ecological disasters, asteroid impacts, etc.
Thus, the option (d) is incorrect.
Organisms are facing several environmental challenges and they try to adapt to those environmental changes. These changes or newly evolved characters are genetically changed and transfer to the next generation. This dynamic evolutionary process is called adaption. The adaptive changes in an organism's physical body or behavior that aids their ability to survive and thrive.
Therefore, the correct answer is option
