Answer:
Language is most objective when based upon evidence.
Step-by-step explanation:
Being objective means sticking to the facts, and not feelings, beliefs, thoughts, or opinions (which were the other three options given). So, that can be applied to a language too. Facts, which are supported by the evidence, are veritable and unfeigned, and not someone`s point of view or something that can be changed under the influence of some factors. In that way, language is objective which makes it fair and correct, and it corresponds with real life.
