To assess which preservation method best maintains vitamin C in fruit, scientists tested chilling and air drying under controlled conditions. Samples were exposed to various durations and storage environments. Vitamin C levels were measured after one week. The researchers found that chilling consistently preserved more vitamin C—even in its poorest outcome—than air drying did in its strongest case, leading them to conclude that chilling is more effective for nutrient preservation.

Which choice best describes data from the graph that support the researchers' conclusion?

ABoth the lowest and highest vitamin C retention levels for chilled fruit slices exceeded 40 milligrams per 100 grams.

BThe least successful chilling attempt still preserved more vitamin C than the most successful result from air drying.

CThe best air-dried fruit slice retained approximately 38 mg of vitamin C, while the most successful chilled sample retained approximately 56 mg.

DThere was a large gap in vitamin C levels between the strongest and weakest results using the chilling method.
