To solve this, we need to count the days from 25th February 2008 to 15th March 2008.
- February 25th to 29th (since 2008 was a leap year): 5 days
- March 1st to 15th: 15 days So, total days = \( 5 + 15 = 20 \) days.
Now, divide 20 by 7 (since there are 7 days in a week), we get a remainder of 6.
Starting from Monday (25th February 2008), moving forward 6 days lands us on Saturday.
Therefore, the correct answer is (B) Saturday.
