Final answer:
The otter had the least amount of change in weight, losing only 2 kilograms, which is the smallest change compared to the other animals mentioned.
Step-by-step explanation:
The question is asking to identify which animal experienced the least amount of change in weight between January and February at the zoo. We need to compare the absolute values of weight changes for each animal. Here is the breakdown of the weight changes:
- Lemur lost 3 kg
- Rhino gained 12 kg
- Otter lost 2 kg
- Penguin gained 4 kg
The least amount of change in weight occurred in the otter, which lost 2 kilograms, compared to the other animals that had changes of 3 kilograms, 4 kilograms, and 12 kilograms. Therefore, the correct answer is: 3) Otter.
