Technical steganography refers to methods that employ digital formats and techniques to conceal information within other types of data. This approach manifests in various forms, such as embedding messages within images, audio files, or even video streams. The key aspect of technical steganography is not restricted to physical means or specific written languages; instead, it leverages any digital medium to achieve the concealment of messages without changing the apparent structure of the host file.

In contrast, options that reference physical means or written natural language focus on forms of communication that do not utilize digital technologies, thus not capturing the essence of technical steganography. Similarly, while visual symbols can be a medium for steganography, they do not encompass the broader range of digital formats that technical steganography employs, which can include a multitude of file types beyond just visual symbols. The answer emphasizes the versatility and comprehensive nature of technical steganography in modern digital communication.
