What do these amendments to the constitution have in common? a)they impact congress. b)they expand voting rights. c)they prevent discrimination. d)they limit presidential powers.

Though there is information listing from the question, I can concur the answer is A)They impact Congress for the following reasons.

1. No legislative document can give, expand, or contract human rights. They simply only state them, and state that they may not be abridged. They are unavailable rights given by God not government. So B can not be correct.

2. Of course wrongful discrimination is bad, but discrimination in general isn't inherently evil, and most importantly, the word discrimination isn't ever mentioned in the United States Constitution. So C can not be correct.

3. While there are amendments to the constitution that limit the terms and clarify the procedure for replacing the president needed, there is no amendment to the United States Constitution that restricts the powers delegated to the president whilst he is currently serving his tenure. So D can not be correct.

4. All amendments effect Congress in some sense, or they would otherwise not exist. Some of the text includes phrases such as "Congress shall make no law..."  or "Congress shall have power to enforce..." "Congress may by law..." and others. So that means A can be correct.
