Which of the following is an example of an individual characteristic of the 4th Generation iPod Classic?

An example of an individual characteristic of the 4th Generation iPod Classic is that it can hold 6,240 songs. Individual characteristics are unique traits that can specifically identify or distinguish one item from another within the same category. This particular example speaks to the device's unique storage capability, indicating how many songs it can hold based on its specific configuration. This is significant because it goes beyond mere physical appearances or condition; it reflects the device’s data storage abilities, which can vary from model to model, contributing to its individuality.

The other choices, while they may describe attributes of the iPod, do not represent individual characteristics in the same way. The color, overall capacity, or condition (such as having a cracked screen) are not unique features that distinctly identify the specific device. Instead, they might pertain to any number of devices of the same model or configuration. Thus, the specific number of songs, as stated in the correct choice, acts as a unique identifier within the context of the device’s capabilities.
