In what way does the shape of a molecule affect how the molecule is
involved with living systems?
a. it determines the weight of the molecule.
b. it determines how the molecule functions.
c. it determines oxidation states present in the molecule.
d. it determines what elements are in the molecule.

It determines how the molecule functions.- B.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

i think it is true since you can test the answer and can use observations to complete it.
