Refer to the graphs below.
The figure shows data from an infant who sucked on a pacifier in order to hear sounds. By comparing graphs B and C, determine which of the following conclusions is supported.
A) The infant can easily tell the difference between any two phonemes.
B) When the infant hears an unfamiliar phoneme, his or her rate of sucking instantly decreases.
C) The less similar two phonemes are, the more likely the infant is to notice a change in sound between the phoneme that is presented first and the phoneme that is presented second.
D) When the infant hears the same phoneme over and over again, his or her rate of sucking increases gradually.

Graph B shows the rate of sucking in response to a familiar phoneme and a different, unfamiliar phoneme. Graph C shows the rate of sucking in response to two different, but still familiar, phonemes. The fact that there is a larger decrease in sucking rate in response to the unfamiliar phoneme compared to the similar, but still different, familiar phoneme supports the conclusion that the less similar two phonemes are, the more likely the infant is to notice a change in sound between them.
