The correct answer is A. Mike and Maria's political beliefs don't always match exactly with their two sisters' opinions

Explanation:

In English, the apostrophe (')  is commonly used to express ownership or possession. According to grammar, the apostrophe followed by an"s" is added to the noun that acts as the owner, except if the noun ends in "s", in this case, it is not necessary to add an "s", but only the apostrophe. On the other hand, if there is more than one noun that acts and owner the apostrophe and "s" should be added individually if the ownership is equally individual or only in the last noun if the ownership is shared.

Considering this, in the sentence presented in the apostrophe should be added in Maria as "Mike and Maria's" considering the political beliefs of both of them  (Maria and Mike) are the same, which means the ownership is shared and in the case of "sisters" the apostrophe should be added, but not the "s". Therefore, the correct sentence is "Mike and Maria's political beliefs don't always match exactly with their two sisters' opinions".
