But it was talking about each of their cars. so why would it be different isn't it like a possessive?

I got it then it would be B

Right.

The correct answer is D) The black car is hers, and the white car is theirs.

To determine the correctly punctuated sentence, we need to understand the rules for indicating possession and plural possessives.

In English, possession is typically indicated by an apostrophe followed by the letter "s" ('s). However, when indicating possession for pronouns, such as "her" and "their," we do not use an apostrophe.

In option A, "her's" and "their's" incorrectly use an apostrophe to indicate possession. Therefore, option A is incorrect.

In option B, "hers" is correctly punctuated, but "their's" still uses an apostrophe to indicate possession, which is incorrect. Therefore, option B is also incorrect.

In option C, "her's" and "their's" both use an apostrophe to indicate possession, which is incorrect. Therefore, option C is incorrect as well.

Option D is the correct answer because "hers" and "theirs" correctly indicate possession without an apostrophe.

So, to recap, the correctly punctuated sentence is D) The black car is hers and the white car is theirs.
