Which choice identifies the compound's structural formula, and what information does the structural formula provide that the molecular formula does not?

Image B represents the structural formula, and only the structural formula allows the molecular
shape to be determined because it shows the position and alignment of the atoms and bonds.

Image B represents the structural formula, and only the structural formula allows the number of
atoms of each element in the compound to be determined because it provides subscripts.

Image A represents the structural formula, and only the structural formula allows the type of
bond formed by the compound to be determined because it shows the element symbols written
in order (metals and then nonmetals).

Image A represents the structural formula, and only the structural formula allows the bond
length of each bond between the atoms of the compound to be determined because it shows the
bonds represented by a line.
