Choice A has my grandparents had last seen before my grandparents were married which does not make sense.
Choice B has an <u>period </u><u>after </u><u>rented</u> an it which does not make sense either
Choice C seems like the proper punctuation and word usage which leads me that this is the <em><u>right </u></em><em><u>choice</u></em>
Choice D says my grandparents had last seen before my grandparents were married which is not the proper usage of the words and hence <u>crosses </u><u>this </u>choice off.
omggg why is people on here sooo talanted .. rose had alot going on try using more suspense to really grab the readers attention... also throw curve balls so it wouldn't be too predictable... don't be shy to make some people mad ...when you end the story make an unpredictable ending
