Answer: It promotes the concept of natural rights.
Step-by-step explanation: If liberty consisted in the freedom to do everything which injures no one else, then it definitely wouldn't be "D" (It supports the separation of government powers.) Considering the title only says the declararion of the "rights of man" or men in general, we can scratch out "C" because it doesn't tell us they're ensuring women other than the fact it would have been listed in the title and description. However, we can say that the description shown is providing the enjoyment of the same rights, but it's not ensuring rights for both genders. And it doesn't denounce a social contract at all, it's talking about freedoms and "assuring other members of the society" with the same enjoyment of the same rights. The answer would have been "A" (It promotes the concept of natural rights.) because it does promote the concept of natural rights throughout reading the whole thing.
