When Int-1, the Interneurons Located on Each Side of a Cricket's

When int-1, the interneurons located on each side of a cricket's body, are experimentally inactivated, the flying cricket does not alter its body orientation in response to ultrasonic stimulation. This finding

A) supports the hypothesis that int-1 is part of the neural circuit that responds to a bat's ultrasound.
B) suggests that the ear receptors located on the cricket's forelegs are less important for detecting ultrasonic calls than the neurons in the central nervous system.
C) caused researchers to reject the hypothesis that because these sensory and processing systems are costly, they will be lost in species that no longer need them.
D) supports the prediction that the flight path of a cricket is controlled by the position of the hindwing.
