The correct option is
A Crayons 3, Crayons 1, Crayons 2
While comparing three things of different sizes, we identify the biggest and smallest objects by comparing one object with the other two objects.
If we compare crayon boxes of different sizes, we identify the biggest and smallest crayon boxes by comparing one box with the other two boxes.
Comparison:
Crayons 1: Bigger than Crayons 3 and Smaller than Crayons 2.
Crayons 2: Bigger than Crayons 2 and Crayons 3.
Crayons 3: Smaller than crayons 1 and Crayons 2.
The correct order of arranging the crayon boxes from smallest to biggest would be
Crayons 3, Crayons 1, Crayons 2.
Hence, Option D is correct.
