To support the inference that "The VO has to be very selective with their produce for their concerts," explicit information from the paragraphs that would be relevant includes the mention of "the vegicians occasionally pack produce in their suitcases in case they can't get the ones they need out of town." This indicates that they are careful and selective about the produce they use, as they prepare in advance to ensure they have the right items even when traveling. This detail emphasizes their need for specific produce to create their performances, thereby supporting the inference about their selectivity.
The option "All of the above" does not provide specific explicit information but rather summarizes multiple points, making it less directly relevant to the inference.
