Solution

✅ Correct Option: 1

A calendar repeats when the total odd days from the given year become 00 and the year type matches.

Counting odd days from 2019 onwards: ordinary years give 11 and leap years give 22. Adding 2019 to 2029: 1+2+1+1+1+2+1+1+1+2+1=141+2+1+1+1+2+1+1+1+2+1 = 14, which leaves remainder 00 on division by 77.

So 2030, also an ordinary year, repeats the 2019 calendar.
