• A. 12
• B. 36
• C. 60
• D. 250

Answer: (D)

Tracking sick leave with a rolling calendar period means using a fixed-length time window that moves forward each month. A window of 250 months (about 20 years) provides a very stable baseline because it includes a large amount of data, smoothing out monthly noise and seasonal effects, so you can see true long-term trends in sick leave usage. As each new month arrives, the oldest month drops off and the newest month is added, keeping the window constant and ensuring the analysis reflects current patterns over a lengthy history. Shorter windows would react more to short-term fluctuations and spikes, whereas the long window supports more reliable planning and policy insights by highlighting gradual changes in behavior.
