Which of the following is the best source of evidence that organization in the primary auditory cortex is tonotopic,and that this organization occurs during a sensitive period in development?
A) animals exposed to pure tones during a certain time in development show more representation of those sounds in the auditory cortex than similar exposure later in development
B) infants who were exposed to pure tones during the last 2 months of gestation are more likely to exhibit absolute pitch
C) animals raised without exposure to sound never develop the ability to hear low frequency sounds
D) infants show a preference for female voices over male voices, and this shapes their auditory cortex to prefer higher frequencies

Animals exposed to pure tones during a specific period in development show more representation of those sounds in the auditory cortex, which indicates the tonotopic organization of the primary auditory cortex. This sensitive period during development suggests that the organization occurs through experience-dependent plasticity. The other options do not provide evidence for tonotopic organization in the primary auditory cortex or its development during a sensitive period.
