Ok. I assume that you have done a little typing mistake when you have written "choice" in place of "chosen" in all answer choices except A. So, I will try to solve this problem presuming that the correct word is "chosen".
First let us look for the error that can be spotted most easily and this calls for the split between "is" and "are". The phrase "a majority of the animals" is a plural subject and thus, requires the use of a plural verb. On account of this, we can safely eliminate answer choice A.
B- Incorrect because of the wrong position of the word "only".
D- Incorrect. We don't need "is". There is already an "are" present in the sentence and we should eliminate the unnecessary uses of the verb form "to be" for the sake of concision.
E- Incorrect Wordier and awkward.
C- Clear Winner. Uses the correct form of verb (plural). No unnecessary uses of the verb form "to be". Grammatically correct and most concise answer.
