What does the word 'torpid' connote?

The term "torpid" is derived from Latin, where it conveys the idea of being sluggish or inactive. It describes a state of lethargy or a lack of energy, suggesting a slow and unresponsive condition. When something is described as torpid, it implies that it is not energetic or active; rather, it is in a dormant or lethargic state. This aligns perfectly with the choice that signifies dullness or sluggishness, capturing the essence of the word's connotation. In contrast, the other options describe states of activity or energy, which do not reflect the meaning of "torpid."
