The organ that controls all the systems and organs in the body is the brain. So, the correct answer is b. Brain .
The brain is part of the central nervous system and it functions as the control center of the body. It processes information received from the senses, coordinates responses, and regulates various bodily functions such as heartbeat, breathing, and digestion. It also manages conscious tasks like thinking, planning, and decision-making.
The central nervous system, which includes both the brain and spinal cord, sends signals to different parts of the body through nerves. This complex communication system helps maintain homeostasis, which is a stable state of internal balance, and ensures that the body's systems work together efficiently.
To sum up, while the nose, heart, and skin all play important roles in the body, it is the brain that acts as the main control organ, managing all other systems and functions.
