D.

A. Mr. Sullivan is being unfair because one tile has equal probability of being selected over another tile.
Since each tile represents a different student, all students should have an equal chance of presenting their final reports first or last. However, if one tile has a higher probability of being selected over another, then Mr. Sullivan's method of drawing tiles is unfair.
