Runner on third base only and there is a base hit to the outfield, whose responsibility is it to cover BR at home plate?

U1, assuming your question involves no umpire chasing.

Since this is standard starting positioning, U3 would rotate to second, U1 would buttonhook and watch BR at first. PU would watch R1 touch home while moving toward a calling position at third. PU needs to communicate when he arrives at third.

As BR touches second and moves to third, U1 would rotate home, communicating that he is covering home.
