Answer

Explanation:

Step1: Analyze option A

Just knowing the range and mean of aquarium A's lizards doesn't mean half are (14 - 15) cm. No data supports this.

Step2: Analyze option B

Mean of aquarium A is (13) cm, mean of aquarium B is (15) cm. Since (15>13), on average, lizards in B are longer.

Step3: Analyze option C

There is no information about the number of lizards in each aquarium.

Step4: Analyze option D

Range of aquarium A: (15 - 9=6) cm. Range of aquarium B: (17 - 14 = 3) cm. So lizards in A vary more.

Answer:

B. On average, the lizards in aquarium B are longer than the lizards in aquarium A.
