Detailed explanation-1: -The correct option is A Homeostasis. Homeostasis is the tendency of the body to seek and maintain a condition of balance or equilibrium, maintaining parameters such as blood pressure, water content, temperature etc around a set point, in its internal environment, even when faced with external changes.

Detailed explanation-2: -Homeostasis is maintained by a series of control mechanisms functioning at the organ, tissue or cellular level. These control mechanisms include substrate supply, activation or inhibition of individual enzymes and receptors, synthesis and degradation of enzymes, and compartmentalization.

Detailed explanation-3: -In homeostasis, body levels of acid, blood pressure, blood sugar, electrolytes, energy, hormones, oxygen, proteins, and temperature are constantly adjusted to respond to changes inside and outside the body, to keep them at a normal level.
