Final answer:

The cell body (or soma) of a mature neuron usually contains centrioles, mitochondria, synaptic vesicles, and rough endoplasmic reticulum.

Step-by-step explanation:

The cell body (or soma) of a mature neuron typically contains several organelles, including centrioles, mitochondria, synaptic vesicles, and rough endoplasmic reticulum.

Centrioles are involved in cell division and are found in most animal cells, including neurons. Mitochondria are responsible for producing energy for the cell through cellular respiration. Synaptic vesicles store and release neurotransmitters that allow for communication between neurons. Rough endoplasmic reticulum is involved in protein synthesis. These organelles play important roles in the functioning of a neuron and support its various activities.

The organelles that are usually found inside the cell body (or soma) of a mature neuron are:

- Mitochondria: These organelles are responsible for producing energy (ATP) for the neuron through cellular respiration.
- Synaptic vesicles: These organelles store and release neurotransmitters, which are chemical messengers that allow communication between neurons.
- Rough endoplasmic reticulum: This organelle is responsible for protein synthesis, and in neurons, it plays a role in synthesizing membrane proteins and proteins for the secretion of neurotransmitters.

Centrioles are not usually found in the cell body of a mature neuron, as they are mainly involved in cell division and are more commonly found in dividing cells. Therefore, the correct options are:

- Mitochondria
- Synaptic vesicles
- Rough endoplasmic reticulum

So, the correct answer is:

A) Mitochondria
B) Synaptic vesicles
C) Rough endoplasmic reticulum
