Answer 2

C, A and B

Explanation:

Tank A holds 40 Liters and 5 fish.

• Volume per fish of Tank A
  `=40 / 5 =$ 8 fish per liter`

Tank B holds 100 Liters and 12 fish.

• Volume per fish of Tank B
  `=100 / 12 =$ 8.33 fish per liter`

Tank C holds 180 Liters and 23 fish.

• Volume per fish of Tank C
  `=180 / 23 =$ 7.83 fish per liter`

Therefore, the volume per fish from least to greatest is:

7.83, 8 and 8.33

These correspond to the tanks: C, A and B respectively.
