Answer: The answer is the B) Europeans used physical punishment to control native populations, just as Prospero punishes Caliban with physical pain.
Explanation: Just to elaborate a little bit on the answer, it can be added that Caliban is Prospero's servant and, when he bitterly complains about the way he is treated (and rightly so, since he was already living in the island before Prospero and his daughter Miranda arrived and Prospero eventually enslaved him), Prospero punishes him with cramps at night, pains and other torments. In Act 1, Scene 2, for instance, Prospero speaks to him in the following terms: "For this, be sure, tonight thou shalt have cramps. Side-stitches that shall pen thy breath up. Urchins / Shall, forth at vast of night that they may work. All exercise on thee. Thou shalt be pinched / As thick as honeycomb, each pinch more stinging / Than bees that made 'em."
