The correct option is B west to east
Sun appears to move from east to west around the earth which means the earth is rotating in the opposite direction. This is due to relative motion of the sun with respect to the earth.
Even though the sun appeasrs to be moving, we know that the sun remains at rest and only earth rotates about its own axis, therefore the motion of the earth with respect to sun will be opposite to that of the sun i.e. from west to east.
