Solution
The correct option is A Cell, nucleus, chromosome, water molecule, oxygen atom
The nucleus is present inside a cell, the chromosome is within the nucleus, a water molecule is smaller than chromosome as the chromosome is a higher compound with nucleotides, and the oxygen atom is a part of the water molecule.
So the correct answer is option A.
