The term "abject" is best described as experienced or present to the maximum degree, often in a negative way. This word typically conveys a sense of extreme misery or degradation, often associated with feelings of hopelessness or despair. In this context, it combines notions of suffering or a state that is utterly wretched, which aligns closely with the meaning provided in the chosen answer.

The other choices do not capture the essence of "abject." Describing something as full of hope and optimism does not reflect the negativity associated with "abject." Similarly, having a lighthearted nature contrasts significantly with the seriousness of the term, as does the idea of living in luxury and comfort. Both of these options suggest a positive or at least neutral state, which is contrary to what "abject" signifies. Thus, the correct choice effectively encapsulates the depth of negativity inherent in the word "abject."
