Final answer:
An iPod can store videos in the MPEG-4 and H.264 formats, which are the standard video codecs supported by the device.
Step-by-step explanation:
The video formats supported by an iPod are MPEG-4 and H.264. These are the two main video codec standards that an iPod can play. Unprotected WMA and WAV are audio formats, and therefore not the correct answer when referring to video files. Thus, the correct answer to the question, 'In what format can video be stored on an iPod?' is a) MPEG-4 and H.264.
