Which of the following best describes orthography?

Orthography refers specifically to the conventional spelling system of a language, which includes rules for how letters and symbols represent the sounds of that language. This makes the method of representing sounds by symbols a key component of orthography, as it encompasses the relationship between spoken sounds and their written forms. Understanding orthography is fundamental in literacy, as it enables individuals to decode and produce written language accurately.

The other choices do not capture the essence of orthography as accurately. While teaching methods and forms of communication are related to language, they do not specifically address the structured system of spelling and symbols that defines orthography.
