Explanation

The question is asking about the name of the process by which an organism maintains its internal environment. This process is called homeostasis. Homeostasis is the ability of an organism to maintain a stable internal environment despite changes in the external environment. It involves a range of physiological and biochemical mechanisms that work together to keep the body's internal environment within a narrow range of conditions. These conditions include temperature, pH, blood sugar level, and salt concentration. Coordination, option A, refers to the ability of various organs and systems of the body to work together in a coordinated manner. Excretion, option C, refers to the process by which waste products are removed from the body. Metabolism, option D, refers to the chemical processes that occur in the body to convert food into energy and other useful substances. Therefore, the correct answer to this question is Option B: Homeostasis. To learn more about homeostasis and related topics, please see the relevant sections of the recommended textbooks.
