A researcher hypothesizes that bee colonies regulate the temperature of their hives through the coordinated behavior of many individuals, such as fanning their wings to circulate air.
Which observation, if true, would most strongly support the researcher's hypothesis?
- A
Bees pollinate many crops important to agriculture.
- B
Bee colonies often contain tens of thousands of individuals.
- C
Some bees can fly several kilometers from the hive.

When experimenters raised hive temperature artificially, large numbers of worker bees gathered at hive entrances and fanned their wings, lowering the internal temperature.
Explanation
A demonstrates the coordinated behavior in response to elevated temperature, with measurable cooling — directly supporting the hypothesis. B, C, and D are tangential.
