Hello.
A. is not correct because neighbor's should not have an apostrophe in it. because with there being an apostrope it would be 'neighbor is' - therefore it should look like this. . . My neighbors pet is the subject of much discussion in our apartment building.
B. is not correct because its should have an apostrophe - therefore, it should look like this. . . It's a known fact that snakes are not popular pets.
C. is not correct because their's is not even spelled correctly and it shouldn't ave an apostrophe - therefore it should look like this. . . There's a story going around the building that Herman got out one day last week.
D. this is the correct answer, since everything is spelled correctly and everything is grammeraly correct. their is used correctly in this sentence. therefore this is your answer.
I hope this helped you!
