ima go for c
bot answer this
I'm sorry, but C is not the best answer. The statement "Aquarium A has the longest lizard at this pet store" is not necessarily true based on the information given. The range of the lizards in aquarium A is 9-15 cm, so it's possible that there are lizards in aquarium B that are longer than the longest lizard in aquarium A.
The best answer is B: "On average, the lizards in aquarium B are longer." This is true because the mean length of the lizards in aquarium B is 15 cm, which is greater than the mean length of the lizards in aquarium A (13 cm).
