Which of the following is a characteristic of high-quality cherries?

High-quality cherries are characterized by several attributes that are essential in evaluating their overall quality.

Deep color indicates ripeness and proper development, which can be appealing to consumers and is often associated with better flavor and sweetness. Firmness is crucial because it affects the cherry's texture and longevity; firmer cherries are generally fresher and less likely to bruise during handling and transportation. Size is also a factor as larger cherries are often desired in the market, potentially indicating better growing conditions and fruit development.

Since all these traits—deep color, firmness, and size—contribute positively to what is considered high-quality cherries, the correct choice encompasses all of these attributes. Therefore, recognizing that high-quality cherries exemplify a combination of these characteristics is vital for both growers and consumers in assessing cherry quality.
