We know that the relation between the sound of a word and its meaning is arbitrary because:

Select one:

A. Different languages have different words that refer to the same objects/concepts.

B. All languages have similar words that refer to some of the same objects/concepts.

C. Onomatopoeic words are similar across languages.

D. Children acquire the language of their environment effortlessly.

E. Onomatopoeic words are in fact different across languages.

Answer: A. Different languages have different words that refer to the same objects/concepts.

Explanation:each language has its own sound that does not resemble the sound from another language.

The word may sound the same but mean something totally different in another language.

As the result it is possibly unfair to expect the same word in one's language that sound the same to mean the same in another language.

We know that the relation between the sound of a word and its meaning is arbitrary because:

A. Different languages have different words that refer to the same objects/concepts.

Explanation:

There are two reasons for this answer. First, only cognates work as a kind of synonym because they come from the same origin. Second, the majority of languages don't share the same origin, rules, inspirations, and applications. Therefore different words refer to the same objects. An example is red, Rojo, aka. All of them mean red.
