The correct answer of this question is : nervous and endocrine systems

Nervous and endocrine systems senses external environment and communicates with andactivates other parts of the body.​

Explanation :

• The major nerves and organs that make up the human nervous system transmit messages to the central nervous system (CNS) informing it of the state of the body and the surrounding environment.
• The neurological and endocrine systems are two types of communication networks in the human body that combine, coordinate, and react to sensory data that the body receives from its environment.
• Chemical communication is used to transmit signals from one cell to another in both the neurological and endocrine systems.

• Nerve cells in the nervous system communicate by means of electrochemistry, which is the process by which chemicals induce an electrical impulse to go from one cell to another.
• This reaction is focused and transient. In order to cause a more extensive and prolonged response, glands discharge hormones into the blood, where they reach the target organs.
