Final answer:
The cell body or soma of the neuron contains the organelles such as the Golgi apparatus, ER, and mitochondria.
Step-by-step explanation:
The part of the neuron that contains organelles such as the Golgi apparatus, endoplasmic reticulum (ER), and mitochondria is the cell body (or soma). The cell body is responsible for maintaining the neuron's structure and functionality, because it houses the nucleus and most of the cellular organelles. While dendrites extend from the cell body to receive messages from other neurons and axons carry signals away from the cell body to other cells, the organelles are primarily located in the soma. Hence, the correct answer to the question is: 1) Cell body (Soma).
