Which of the following best fits the definition of "turbulent"?

The term "turbulent" is most accurately reflected in the description of something that is violent and disorderly. It often conveys a sense of chaos, unrest, or disturbance, whether in physical environments, like turbulent waters, or in metaphorical contexts, such as turbulent emotions or periods in history. When conditions are described as turbulent, it suggests a lack of stability and the presence of significant disruption or agitation.

The other options contrast directly with this definition, as they imply calmness, order, and predictability, which are antithetical to the idea of turbulence. Consequently, option C captures the essence of the word, making it the best choice.
