Answer;

The teacher packed picnic lunches for all the students—which they loved—and ate lunch outside with them at recess.

Explanation;

A nonrestrictive clause is a type of adjective clause that provides additional information about a word whose meaning is already clear. Nonrestrictive clauses often begin with the word which and are always set off with commas.

In this case, A is correct 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 punctuation.
