Well To me I think it would be C: Both 1 and 2 Because When you look at the arrow and know the direction of Clockwise going right, you can already mark 3 off because the arrow would be going Left and pulley 1 and 2 are going right (Pully 1 is going right but down, so that would count.).
You can infer that the planets year is longer than Jupiters, but still shorter than Saturn's year, so you can add up Jupiter's and Saturn's orbit and divide by 2 to get more information about this "new planet".
