Final Answer : B, Explanation :  When a very short time period is used for a regression study, accounting measurement errors are more likely to occur due to the limited amount of data being used. Coping with inflation and conducting time and motion studies may still be necessary, but they are not directly related to the use of a shorter time period for the regression study.
