उत्तर: D

Even combining the gain rate and elapsed time, we can determine how far off the clock currently is, but without knowing after how many total hours it takes to gain a full 12-hour cycle (720 minutes) to show correct time again, the specific future time of correction cannot be found from this data alone.
