A study was conducted to determine which school meal ought to be removed from the weekly rotation. Every student in the school was asked to rank their top three school lunches. Tuna melts were found to be the least-favored option, with only 7.8 percent of students ranking tuna melts in their top three choices.

The correct response is: This is a survey since opinions were collected.
In this case, the study involves collecting preferences from students about their favorite school lunches, which fits the definition of a survey. There is no treatment applied to any subjects, and the study does not investigate a cause-and-effect relationship, making it distinct from experimental or observational studies.
