SAT Inferences Question

To combat predation by the big brown bat and other insectivorous bats, many moth species, including Xylophanes tersa, emit ultrasonic pulses that, in some cases, disrupt the echolocation bats rely on for foraging. Some scientists have hypothesized that this capability evolved because it imposes a lower metabolic cost than does the alternative mechanism of producing chemicals that render moths noxious to bats. Pablo Sebastián Padrón et al. investigated the acoustic properties of moths' ultrasonic responses to audio of bat echolocation and then assessed the palatability of the ultrasound-producing moths. They found that several moth genera that emit ultrasonic pulses capable of disrupting bat echolocation are unpalatable to bats, suggesting that ## Which choice most logically completes the text?
