A leap year has 366 days or 52 weeks and 2 odd days.

The two odd days can be {Sunday,Monday},{Monday,Tuesday},{Tuesday,Wednesday},{Wednesday,Thursday},{Thursday,Friday},{Friday,Saturday},{Saturday,Sunday}.

So there are 7 possibilities out of which 2 have a Sunday.

So the probability of 53 Sundays is 2/7.

option 2 is right . leap year ka 2/7 hota hai aur normal year ka 1/7 hota hai.
