I'd go for C: the original text focuses a lot on many types of animals so B would not be good (it talks only about one animal species), and A for the same reasons: why choose only one type of animals?Also D completely forgets about all the animals.I think C gives the most informative summary.
I think the correct answers are grammar, spelling, pronunciation and vocabulary. These things are the four characteristics of standard English. It refers to whatever form of the English language is accepted as a norm in an English-speaking country.
I wouldn’t know this fr but I say B because it’s better when you understand
