Final Answer :
B
Explanation :
Choice B accurately identifies the nutritionists as the researchers conducting the study, the 300 freshman students as the cases, the relevant variables collected (age, dining hall visits, exercise, weight), the time frame (freshman year), the location (large university), and the data collection method (weekly surveys). Choice A misidentifies the cases as the nutritionists, while Choice C misidentifies the location as only the dining hall. Choice D is incorrect as there is no indication that the nutritionists are the cases being studied. Choice E is incorrect as it suggests phone surveys instead of the stated weekly surveys.
