The correct answer is B) "Green tea is really good for you because it's full of anti-oxidants."

To identify the correct sentence with no punctuation, spelling, or grammar mistakes, we need to analyze each option:

A) This sentence has a mistake in punctuation. A comma is used after "you," which is incorrect. The comma should be placed after "good for you." Additionally, "anti oxidants" should be written as "anti-oxidants" with a hyphen.

B) This sentence is correct. The punctuation is accurate, and "anti-oxidants" is spelled correctly.

C) This sentence has two mistakes. First, it lacks the apostrophe in "it's" to indicate the contraction of "it" and "is." Second, "antioxidants" should be written as one word, instead of separate words.

D) This sentence has a mistake, similar to option C. It lacks the apostrophe in "it's." The spelling of "antioxidants" is correct in this option.

Therefore, the correct answer is B) "Green tea is really good for you because it's full of anti-oxidants."
