If 17 December 2012 was Monday, then what was the day of the week on 18 November 2020?

Given: 17 December 2012 was Monday

18 November 2020 = ?

Total number of odd days between 17 December 2012 to 17 December 2020 = total years - (2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020)

odd days = 1 + 1 + 1 + 2 + 1 + 1 + 1 + 2 = 10

odd day for 10 days, 10 divided by 7 , reminder = 3

the day at - 17 December 2020 = Monday + 3 = Thursday

18 November 2020 to 17 December 2020 = (30 - 18) + 17 = 12 + 17 = 29 days

we added already 29 days extra.

odd day for 29 days, 29 divide by 7 = reminder = 1

the day at- 18 November 2020= Thursday -  1 = Wednesday.

option D is correct.
