What is described as ‘emotionally charged and vigorous’?

The term "torrid" is often used to describe something that is emotionally charged and vigorous, typically conveying intense passion or fervor. It originates from contexts that suggest heat and intensity, making it suitable for describing situations or emotions that are lively and full of energy. When an experience or a situation is characterized as torrid, it implies a strong engagement of feelings, suggesting fervency and dynamism.

In contrast, the other options refer to states that lack the intensity and vigor associated with "torrid." Terms like "dull," "frigid," and "listless" imply a lack of energy, enthusiasm, or warmth, making them unsuitable for conveying the emotionally charged connotation of the correct answer.
