Explanation:

Here we need to break days till 14^th Mar 2393.

Complete years = 2392

Odd days in first 2000 years = 0
Odd days in next 300 years = 1
Odd days in next 92 years (23 leap and 69 non-leap years) = 23 × 2 + 69 × 1 = 115.

∴ Odd days in complete years = 0 + 1 + 115 = 116 odd days.

∴ Odd days in complete years = Remainder (116 ÷ 7) = 4 odd days.

Incomplete year (2393, a non-leap year)

Jan = 31,
Feb = 28
Mar = 14

∴ Odd days in incomplete year = 31 + 28 + 14 = 73 odd days = 3 odd days.

∴ Total odd days till 14^th Mar 2393 = 3 + 4 = 7 odd days = 0 odd days.

∴ Day of the week on 14^th Mar 2393 will be 0 days after Sunday i.e., Sunday.

Hence, option (b).
