If someone is feeling apathetic, which of the following terms could best describe their condition?

The term that best describes someone feeling apathetic is "torpid." When someone is apathetic, they exhibit a lack of interest, enthusiasm, or concern, which aligns closely with the meaning of "torpid." This word suggests a state of inactivity or lethargy, indicating a sluggishness in emotional or physical response. It highlights an overall sense of indifference, making it a fitting choice for describing an apathetic condition.

Contextually, the other options do not encapsulate this state as accurately. "Ubiquitous" refers to something that is present everywhere at the same time, which does not relate to feelings of indifference. "Tawdry" pertains to something that is cheap or gaudy, often in terms of material possessions or appearance, and does not convey emotional disengagement. "Tetchy," on the other hand, describes someone who is irritable and easily annoyed, which is quite the opposite of apathy, as it implies a heightened emotional state. Thus, "torpid" is the most appropriate term to describe a feeling of apathy.
