Answer:
A. Arbitrariness of the sign
Read Explanation:
Onomatopoeia refers to words that imitate or resemble the natural sounds they describe.
These words have a more iconic relationship between their form (signifier) and their meaning (signified).
For example:
"buzz" imitates the sound of a bee,
"clang" imitates the sound of metal hitting metal.
Saussure viewed most linguistic signs as arbitrary (the connection between the signifier and the signified is based on social convention), but onomatopoeia seems to challenge this idea because there is a more natural connection between the sound and the object or action it represents.
However, Saussure still considered onomatopoeic words to be part of the system of signs because even they depend on social agreement to be understood in context.
