How would you describe something that is immaculate?

Immaculate describes something that is entirely free from flaws or mistakes, and it is most commonly associated with being perfectly clean and tidy. When referring to cleanliness, this term conveys a sense of being pristine or in an immaculate condition, which aligns with the choice that indicates complete neatness and cleanliness.

The other options do not capture the essence of being immaculate. Something that is excessively sweet pertains to taste, which is unrelated to the cleanliness or flawlessness implied by immaculate. The reference to ostentatious and lofty style describes something stylish or grand, again missing the focus on cleanliness. Lastly, describing a very steep cliff does not relate to the concept of cleanliness or perfection at all. Thus, the description of something that is immaculate as completely neat and clean is the most accurate and fitting interpretation of the term.
