The increase in sucking rate when the sound /l/ is played again indicates that the infant can detect a difference between /r/ and /l/. This increase in response is an example of dishabituation, which occurs when a new stimulus is presented following a habituated stimulus, revealing that the infant can discriminate between the two stimuli. Therefore, the correct choice is C) dishabituation; can detect the difference between /r/ and /l/.
