Final answer:
The act of using symbols to compose meaningful text for communication is known as writing, which is underpinned by the principles of semiotics. Option b is correct.
Step-by-step explanation:
The process of using symbols to create meaningful text or sentences which will serve as a medium for communication is commonly referred to as writing. Writing involves the use of a language's set of symbols, such as the alphabet, to construct words and sentences that convey ideas, thoughts, and information. Language is a system of these symbols, and it serves not only for communication but also as a means to transmit culture. Semiotics, or the study of signs, underpins our understanding of written communication.
These signs can include letters, pictographs, hand gestures, and even body language in the case of sign language. Effective writing and the understanding of these symbols are critical for creating text that is understandable to a target audience. It allows individuals to communicate their thoughts and messages to others in a clear and organized manner. For example, when someone writes a letter or an essay, they are using symbols (words) to create meaningful text that can be understood by others.
