Correct Answer - Option 4 : Monday
The logic follows here is :
4 days after Sunday is Thursday.
5th of the month falls on Thursday.
To find the day on the 16th of the month,
We have to find the number of odd days between the 5th and 16th of the month.
Number of days = 16 - 5 = 11.
Odd days = Remainder of (11 ÷ 7)
Odd days = 4.
Thursday + 4 = Monday.
Thus, the day on the 16th of that month will be Monday.
Hence, the correct answer is "Monday".
