B My sister who exercises every day, is coming over for dinner.My sister who exercises every day, is coming over for dinner.
C My sister, who exercises every day, is coming over for dinner.My sister, who exercises every day, is coming over for dinner.
D My sister, who exercises every day is coming over for dinner.
C My sister, who exercises every day, is coming over for dinner.
The correct answer is C) My sister, who exercises every day, is coming over for dinner.
This option correctly uses commas to set off the nonrestrictive clause "who exercises every day." The commas indicate that the information within the clause is not essential to the main sentence.
To determine which answer choice correctly uses commas to punctuate the sentence, we need to identify the phrase that provides additional information about "my sister." This additional information is called a relative clause.
In this case, the relative clause is "who exercises every day." The correct placement of commas in a sentence with a relative clause depends on whether the information provided by the clause is essential or non-essential to the meaning of the sentence. If it is essential, no commas are used. If it is non-essential, the relative clause is set off by commas.
Looking at the answer choices:
A. Incorrect: This answer choice does not use any commas to set off the relative clause, which suggests that the information provided is non-essential. However, in this context, the information about the sister exercising every day seems essential to understanding who is coming over for dinner.
B. Incorrect: This answer choice incorrectly uses a comma after "day" instead of before "who." Commas should be placed before and after the relative clause when it is non-essential, not within the clause.
C. Correct: This answer choice correctly uses commas to set off the relative clause "who exercises every day." This suggests that the information about the sister exercising every day is non-essential to the meaning of the sentence.
D. Incorrect: This answer choice does not use any commas to set off the relative clause, suggesting that the information provided is non-essential. However, as mentioned earlier, the information about the sister exercising every day seems essential in this context.
Therefore, the correct answer choice is C: "My sister, who exercises every day, is coming over for dinner."
