Packet transmissions are a method of data communication that breaks down information into smaller packets for efficient transport over a network. This method is versatile and can encompass various types of data.

Text data is the most commonly associated type of information transmitted via packets, particularly in computer networking and amateur radio contexts. It is straightforward and has been the foundation of many early packet radio applications.

Audio and video data can also be transmitted using packet protocols, thanks to advancements in technology that allow for the digitization of these formats. Audio data can be transmitted for voice communications over radio frequencies, whereas video data, although more demanding in terms of bandwidth, can also be sent as packets, allowing for higher-quality transmission of moving visual information.

Because packet transmission is designed to handle multiple types of data efficiently, its capability is not limited to one format. Instead, the entire spectrum of audio, video, and text data is included in its potential uses. Thus, the correct answer acknowledges this all-encompassing feature of packet transmissions by indicating that all types of data can be included.
