A. Survey the first 100 movie-goers leaving the movie complex
B. Survey 100 randomly selected movie-goers that just watched a drama movie
C. Survey 100 randomly selected movie-goers in the 10-year-old to 40-year-old age bracket
D. Survey 100 randomly selected movie-goers from the entire complex..

C. Survey 100 randomly selected movie-goers in the 10-year-old to 40-year-old age bracket would be the best sample for the survey as it targets a specific age group that is likely to be interested in snacks and eliminates potential bias based on movie genre or timing of the survey.
