How is "turbulent" best defined?

The word "turbulent" is best defined as very excited or disorderly. This term often describes situations that are chaotic, marked by unrest or disturbance, and can refer to physical states like rough seas or stormy weather, as well as emotional states where there is confusion or agitation.

In contexts where something is described as turbulent, it implies a lack of stability or a sense of upheaval. For example, turbulent times in history can indicate periods of conflict and unrest. This connection to disorder and excitement aligns perfectly with the definition provided in the correct answer.

The other options do not capture the essence of "turbulent." Describing something as very peaceful and calm, orderly and smooth, or consistent and stable reflects states that are the opposite of chaos or excitement, highlighting why they cannot be the correct definition of "turbulent."
