What is the meaning of "ignoble"?

The term "ignoble" refers to a lack of nobility, both in character and in various qualities or purposes. It is often used to describe actions or behaviors that are considered unworthy or dishonorable. The core of its meaning encompasses a sense of degradation or baseness, indicating a failure to meet ethical or moral standards.

In this context, the correct choice accurately captures the essence of being devoid of noble qualities, which is fundamental to understanding the concept behind "ignoble." It serves to emphasize the idea of shamefulness as opposed to admirable traits.

The other options do not align with the definition of "ignoble." For example, stating that something has high moral qualities, is noble in action, or possesses distinguished heritage directly contradicts the meaning of the word. Thus, the correct choice conveys the intended meaning effectively.
