The most logical completion of the text is:
(Choice C) depictions of food in Dutch paintings of the period should be taken as realistic representations of Dutch eating habits.
This choice directly relates to the conclusion drawn from the evidence presented in the text—that the presence of lemons, a high-cost imported fruit, raises questions about the accuracy of depictions of dairy products as reflections of everyday eating habits in Dutch life. The contrast in frequency of these food items in paintings suggests that these artworks may not represent typical Dutch food consumption.
