The National Health and Nutrition Examination Study (NHANES) had a random sample of 9317 participants recall their diet over the past 24 hours. The information in this sample was used in a recent study that found that, on average, 57.9% of the calories eaten by participants were obtained from ultra-processed foods that include substances not used in culinary preparations, such as flavors, colors, sweeteners, emulsifiers, and other additives. One of the limitations of the study reported by the authors was the dependence on the dietary recall of individuals. The authors were concerned with: (Choose one and explain why in 1-2 sentances) A) response bias B) undercoverage C) overstratification
