41. A Ferris wheel is turning at a constant speed during 1 of its rotations. Let t represent the time that has elapsed since the wheel started turning and let h represent the height above ground level of a certain seat on the wheel. The seat is at its minimum height at t = a seconds and is at its maximum height at t=b seconds. One of the following graphs represents the relationship between t and h during this rotation. Which one?
