2001 to 2002:
- 2001 is a non-leap year, so it has 365 days.
- 365 days = 52 weeks + 1 day.
- Therefore, 1st January 2002 was Tuesday (Monday + 1 day).
2002 to 2003:
- 2002 is a non-leap year, so it has 365 days.
- 365 days = 52 weeks + 1 day.
- Therefore, 1st January 2003 was Wednesday (Tuesday + 1 day).
1st January 2003 to 26th January 2003:
- The difference between 26th January and 1st January is 25 days.
- 25 days = 3 weeks + 4 days.
- Therefore, 26th January 2003 was Sunday (Wednesday + 4 days).
Therefore, 26th January, 2003 was a Sunday.
The correct answer is Option 2.
