- A.

Answer: Option D
Explanation :
A normal year has 52 weeks and 1extra day.
∴ 365 = 52 × 7 + 1
A leap year has 52 weeks and 2 extra days.
∴ 366 = 52 × 7 + 2
There are 30 extra days between 1971 and 2001.
In this period there were 8 leap years, therefore another 8 extra days.
∴ 38 = 7 × 5 + 3
∴ We are left with 3 extra days.
If 9/12/2001 is a Sunday, then 12/12/1971 was a Sunday and 9/12/1971 was a Thursday.
Hence, option 4.
