Final answer:
The correct punctuation for the sentence is option B) 'something coming to her, and she was waiting for it,' which places a comma before the coordinating conjunction 'and.'
Step-by-step explanation:
When considering corrections for punctuation in the sentence presented, the option that fixes the mistake is B) something coming to her, and she was waiting for it. Here, we add a comma before the coordinating conjunction 'and' to separate two independent clauses.
This is in line with standard English punctuation rules which state that when two independent clauses are joined by a coordinating conjunction, such as 'and,' a comma should precede the conjunction. Hence, the correct sentence is: 'She felt something coming to her, and she was waiting for it'.
No additional commas are needed after 'something' or before 'for it' as those would create unnecessary pauses in the sentence. Options A, C and D are incorrect because they either lack the necessary comma or add commas where they are not required.
