The correct option is C Saturday
We know 12th is Wednesday. Since 1 week is 7 days, every day repeats after 7 days. So 12 + 7 = 19.
The 19th will be Wednesday. Now lets count number of days it takes to reach 22nd.
22 - 19 = 3 days.
so the third day after Wednesday will be, Saturday.
So the answer is Saturday.
