Solution
The correct option is C Stop watch
A sundial may only have scale marks representing the hours of daylight; it would have a least count of an hour. A stop watch used to time a race is more precise at measuring time intervals than the sundial because it has more "counts" (scale intervals) in each hour of elapsed time.
