Given: 1st January, 2001 was Monday.
Now,
2001 is an ordinary year as it is not divisible by 4.
In an ordinary year, there are 365 days.
The number of days between 1st January, 2001 to 31st December, 2001 is calculated by excluding the starting day:
= 30 (January) + 28 (February) + 31 (March) + 30 (April) + 31 (May) + 30 (June) + 31 (July) + 31 (August) + 30 (September) + 31 (October) + 30 (November) + 31 (December) = 364 days.
= 364 days ⇒ 364/7 = 52 weeks and 0 odd days.
So, 31st December, 2001 will be Monday + 0 = Monday.
(Note: In an ordinary year, the first day and the last day of the year are always the same.)
Hence, the correct answer is "Option 3".
