B) The mean spatial perception score of children who take the course on spatial concepts is significantly higher than the average score of children who don't take the course.
C) The mean spatial perception score of children who take the course on spatial concepts is not significantly higher than the average score of children who don't take the course.
D) The mean spatial perception score of children who take the course on spatial concepts is higher than the average score of children who don't take the course.
