Which choice best describes something that displays "panache"?

Something that displays "panache" embodies a sense of distinctive style and flair. The term "panache" typically refers to an attractive combination of confidence, elegance, and spirited originality. Therefore, a choice that highlights a quality that is distinctive and stylish captures the essence of what it means to have panache.

The other options, which suggest being ordinary, conventional, or plain, lack the flair and uniqueness associated with the term. They describe qualities that do not convey the vibrant and stylish characteristics that are integral to the idea of panache. Thus, the choice that best reflects the lively and stylish connotation of "panache" is the one that emphasizes being distinctive and stylish.
