The question is asking if instant noodles (方便面), Lao Hu’s snacks (), or mineral water () are edible.
All three items can be consumed and considered food. Instant noodles are a type of processed noodle dish, Lao Hu’s snacks refer to various types of snack foods like chips, crackers, or puffed rice, and mineral water is simply a refreshing beverage. So, the answer would be yes, they are all edible!
