What is indicated by the term "reading and writing" in the context of language?

The term "reading and writing" in the context of language primarily refers to the interaction with written forms of communication. This encompasses the ability to interpret written text (reading) and produce written language (writing). The phrase indicates an understanding that written language serves as a permanent record of ideas, messages, and meanings, allowing individuals to convey thoughts and information beyond immediate spoken interaction.

Written language can preserve meaning in a way that spoken language cannot, capturing nuances and details that can be referenced time and again. This permanence of meaning markers makes option B the most appropriate answer. In contrast, the other choices address different aspects of communication that do not directly relate to the reading and writing process: natural conversation involves spoken language, non-verbal cues point to gestural or body language communication, and spontaneous language use pertains to the immediacy of oral communication rather than the structured permanence of written language.
