What is the best way to revise this sentence?

Sometimes a purchase doesn't live up to all the things it's advertising says about it.

A. Sometimes a purchase doesn't live up to what it says.
B. Somestimes a purchase doesn't live up to it's advertising.

C. Sometimes a purchase does live up to all the things that it says.

D. Sometimes a purchase doesn't love up to all it's advertising about it?

#1 - None of the sentences are correct because the word should be "its" not "it's" -- the second of which is a contraction meaning "it is."

#2 - Go through all of them and make sure every instance of "it" or "its" makes a clear reference to a noun earlier in the sentence. If it's not clear what "it" is referring to, then that sentence is incorrect.

Please repost and let us know what you think.

yes they are "it" sorry I put "it's" by accident

A and C are not good because of the word "says." Does the purchase talk?

So -- which is better? B or D?

I believe D

I disagree. B. says the same thing, but in fewer words. The words "about it" are redundant.

Oh isee what you mean!

Ms. Sue is right. D has wordiness and redundancy in it.
