CorrectNot quiteAnswer D

Correct answer: D

Explanation

  1. From 1 March 2027 to 1 March 2028 there are 366 days, because 29 February 2028 falls in between.

  2. 366 mod 7=2366 \bmod 7 = 2, so the day moves two places on: Wednesday.

Worth noting

A one-day shift is right for an ordinary year; this span includes 29 February.
