The chemical formula of a compound express the atoms by which the molecule is formed and the ratio of the atoms in which they are combined.
The space filling model of a compound describe the electron density in the compound of each atom.
The ball and stick arrangement of a compound describe the way in which the molecules are present in three dimensions.
The structural formula state the number of atoms present in the molecule, the type of element or atom present in the molecule and the way in which they are arranged closely which is the bond.
Thus only the structural formula only will cover all the options as stated.
