The fact that the infant stopped paying attention to both "ga" and "ta" suggests that she is not perceiving a difference between the two sounds. This is known as habituation, where repeated exposure to a stimulus causes a decrease in response. If the infant were able to perceive a difference, she would likely show renewed interest when the sound changed from "ga" to "ta." Therefore, the best choice is B, cannot perceive the difference between the two sounds.
