• If today is Monday, Yesterday was Sunday. Now B should lie on monday so Sunday was NOT one of the days he lies on...Correct. And C shouldn't lie on monday so sunday was one of the days he lies on....Incorrect. So it's not Monday.
  
  If today is Tuesday, Yesterday was Monday. Now B should lie on Tuesday so Monday was NOT one of the days he lies on...Incorrect. So it's not Tuesday.
  
  If today is Weds, Yesterday was Tue. Now B should lie on Weds so Tues was NOT one of the days he lies on...Incorrect. So it's not Weds.
  
  If today is Thurs, yesterday was Weds. Now B should NOT lie on Thurs so Weds
