Question : Which sentence contains a nonrestrictive clause and is punctuated correctly?
Answer : A, The teacher packed picnic lunches for all the students—which they loved—and ate lunch outside with them at recess.
Why : because after students the appropriate punctuation would be a coma but in this case its a line. B is incorrect since after "student's" it should have a line/comma. C is incorrect since after loved it should have a comma/line. D is incorrect since there is no correct punctuations.
