C. Suzie, my best friend, is also an amazing athlete.
It is the sentence that does not contain any errors in comma usage.
Usage of commas
1) to separate items in a series
2) to separate coordinating adjectives
3) to separate two independent clauses (compound sentence)
4) to separate the introductory words from the independent clause.
5) to separate nonessential words, phrases, and clauses
* All choices contain an "appositive". An appositive renames the subject.
My best friend is an appositive for Suzie.Thus it is enclosed by commas to separate it from the rest of the sentence.
Correct sentence: The weather guy said that it was supposed to rain, but I don't see a drop coming from the sky yet!
A comma is needed to separate the independent clause after rain. - True.
A comma is needed to correctly punctuate the compound sentence- True
The answer is D!
Hope this helps :)
