Anagram is a word, phrase, or name formed by rearranging the letters of another. I don't think this is it because they is no words that were rearranged.
Aphorism is a pithy observation that contains a general truth. This could be true!
Analogy is a comparison between two things. This is not it because there are not two things being compared.
Allusion is an expression designed to call something to mind without mentioning it explicitly; an indirect or passing reference. This is not it because this sentence is explicit meaning it is very straight foward.
Out of all four of those... I would go with Aphorism.
I personally think it might be D but I could be wrong and it might be c so I suggest go with C first then D or if you want you can go D first then C its all up to you! :) <3
