Correct Answer: Monday

Solution : Given:
5 November 2019 was Tuesday.

The number of days from 5 December 2011 to 31 December 2011 = 26
The number of days from 1 January 2012 to 31 December 2018 = 366 + 365 + 365 + 365 + 366 + 365 + 365 = 2557
The number of days from 1 January 2019 to 5 November 2019 = 309

So, the total number of days = 26 + 2557 + 309 = 2892
Now, divide 2892 by 7 to get the odd number of odd days.
Number of odd days = 2892 ÷ 7 = 1 (remainder)

5 November 2019 was Tuesday.
Thus, 5 December 2011 = Tuesday – 1 = Monday

So, Monday was the day of the week on the 5 December 2011. Hence, the third option is correct.
