Which of the following describes a person who feels lassitude?

A person who feels lassitude is experiencing a state of weariness, fatigue, or a lack of energy and interest. This term is often associated with a sense of tiredness or a casual, relaxed attitude that can lead to a diminished enthusiasm for tasks or activities. When someone is in a state of lassitude, they may struggle to muster the energy needed to engage actively with their surroundings or fulfill commitments.

In this context, the correct description is that they lack interest or energy. The other choices depict states of high energy, excitement, motivation, or alertness, which directly contrast with the feelings associated with lassitude.
