Which of the following best describes "unbridled"?

The term "unbridled" refers to something that is uncontrolled or lacking in restraint. This word often describes emotions, actions, or desires that are free from any limits or restrictions. For example, one might speak of "unbridled enthusiasm," implying a level of excitement that cannot be contained or guided.

In this context, the correct answer captures the essence of the word accurately. It highlights the absence of boundaries or moderation, indicating something that is fully expressed and unfettered. This understanding is crucial when interpreting literature or language that employs strong imagery associated with freedom or excess.

The other choices do not align with the meaning of "unbridled." For instance, expressing feelings in a restrained manner conveys the idea of control and moderation, which is in stark contrast to being unbridled. Similarly, marked by gentleness and kindness suggests a calmness that wouldn't fit the concept of something wild or lacking restraint. Lastly, exhibiting mature qualities at an early age implies a level of composure and seriousness that also contradicts the idea of being unbridled. Therefore, the correct answer effectively embodies the core meaning of the word.
