Which of the following sentences uses a comma to set off a nonrestrictive clause?
A. Mom likes her new smartphone, which got excellent reviews online.
B. She has added the contacts for family members, friends, and work.
C. The phone comes with a case, and it has her initials on it.
D. Mom had a coupon, so the phone was quite affordable.
The correct answer would be B being that the commas seperate the different contacts she saved. Always remember commas go between a series of things, or a sentence that needs to be seperated.
