A. Monday
B. Tuesday

48 is of 7k-1 form, hence it would wednesday-1 = tuesday (B)

The answer to this question is fairly easy.We don't have to use all the maths for such kind of questions and should rather save our energy for the tougher ones.So, let's use a little common sense.

Assume today is 31 dec and on 1st Jan that happens to be Wednesday I have to do something very important that I'm postponing till the 48th day of the year.

We all know that there are seven days in a week.So, 7*7=49.If the 1st January is Wednesday, so it will also be Wednesday on the 49th day of the year. Half of our job is almost done.We need to figure out which day will it be on 48th.Since we know that 49th is Wednesday so It will be Tuesday on 48th.
Thus, the correct answer is B.

Expected completion date is Wednesday; it's postponed for 48 days = 7 weeks - 1 day => we just need to go back 1 day, so the solution is Tue. => B

For this question, you may also fall into the trap of calculating which day is it in Feb (I almost falled in it in the first few secs).
