d). The two are still synchronized but run slowly
Explanation:
Here Albert is stationary and Henry is running with a constant velocity carrying a stopwatch and a light clock which are both synchronized when they are at rest. Now when both the clock are moving at the same constant speed, then they will remain synchronized and will show the same time. But they will definitely run slow for Albert because Albert is at rest with respect to the two clocks. Observers measures clocks that move relative to them as running slow. This is given by Theory of relativity that when clocks are moving they run slow because everything is relative to each other and it depends on our frame of reference.
