What best describes the term "serene"?

The term "serene" is best described as calm and peaceful. It evokes an image of tranquility and a lack of disturbance, whether in an environment or a person's state of mind. When something is described as serene, it suggests a sense of stability and harmony, such as a still lake at dawn or a quiet room where meditation is taking place. This sense of peacefulness is key to understanding the term, contrasting sharply with other descriptors that imply agitation or conflict. Consequently, the other choices present opposing qualities that do not align with the definition of "serene."
