Veronica L. Bura, Akito Y. Kawahara, and Jayne E. Yack investigated the evolution and function of sound production in silk moth and hawk moth caterpillars. They found that during harmless simulated attacks on caterpillars, 33% of the tested species produced sound, which ranged from clicks in Antheraea pernyi to whistles in Phyllosphingia dissimilis. A second research team has claimed that caterpillars use these sounds primarily to communicate with other members of their species.
Which finding, if true, would most directly challenge the second team's claim?
Among the caterpillar species that produced sound in response to simulated attacks, no individuals produced sound in the minute before the attacks, but the vast majority of individuals produced sound once the simulated attacks began.
A
Most of the caterpillar species that were found to not produce sound in response to simulated attacks have been observed producing sound during encounters with other members of their species.
B
Caterpillars that were found to produce sounds in response to simulated attacks are typically solitary and were tested in isolation.
C
The sounds caterpillars produced in response to the simulated attacks lacked acoustic characteristics that would make them audible to bats, lizards, or birds, some of the most frequent predators of caterpillars.
D
