Language is which of the following? select all that apply. a system of signs representing ideas any means of communication arbitrarily constructed governed by rules

I'm not sure where the options separate, but if my assumptions are correct and there are two, I believe they are both correct.

I think that everything is correct. Language is a system of signs representing ideas and, also, any means of communication arbitrarily constructed governed by rules.

Explanation:

A language is a system of communication, represented often by written signs or sounds, that is arbitrarily ruled after some time of use by a group of people. There are a lot of languages, of course the ones that each country has and that we already know, but there are also visual languages, sign languages, audio language, etc. The creation of these languages, although arbitrarily constructed, has the objective of making it easier for everyone inside a determined group to communicate.

for the comment!
