B.) Take samples from the same location each time.
Explanation:
The original answer choices to this question are the following:
- Provide details about the creatures in the "other" category.
- Take samples from the same location each time.
- Collect samples from nearby lakes for comparison.
- Use a more sophisticated net to collect smaller creatures.

Some areas of the lake will have more or less wildlife depending on what predators and prey live. She must have a control variable in this survey, otherwise her data will not be correct.
Hope this helps :)
