With the increase of  the number of resonance structures,  the entropy of a molecule also increases. Hence, Option A is correct.
<h3>What is a 
molecule?</h3>
A molecule is the smallest particle which is a combination of two or more atoms of a substance that are held together. For instance, H2O (water), O3 (Ozone), and many more.
In the substance, there are all the properties like physical and chemical properties which are required by them. When there is increase in any of the components in the  resonance structure, there is increase in the molecule also.
Thus, Option A is correct.
