Which sentence should be revised to include commas to set off a nonrestrictive element?

A nonrestrictive element adds extra information that is not needed to identify the noun and is set off with commas. In D, “which we watch together” adds information about the TV show, so the sentence should read: “The TV show, which we watch together, airs on Friday nights.” The other choices use phrases or clauses that identify which car, game, or tree is meant.
