The two structures at the right of the image are the greatest contributors to the resonance structure of malachite green.
<h3>What is resonance structure?</h3>In some cases, one single structure is insufficient to explain the properties of a substance. Now, we know that in such cases we have to invoke more than one structure in order to efficiently discuss the chemistry of the compounds in question.
In this case, we can see from the image that the three structures of malachite green are all resonance structures. However, the two structures at the right hand side are the greatest contributors because they are more conjugated. Hence, the two structures at the right of the image are the greatest contributors to the resonance structure of malachite green.

Answer: Option (c) is the correct answer.
Explanation:
It is known that when Gibb's free energy, that is, has a negative value then the reaction will be spontaneous and the formation of products is favored more rapidly.
Activation energy is defined as the minimum amount of energy required to initiate a chemical reaction.
So, when reactants of a chemical reaction are unable to reach towards its activation energy then a catalyst is added to lower the activation energy barrier so the reaction can take place rapidly.
Since, the given reaction has low activation energy. Therefore, there is no need to add a catalyst.
And, when value of is positive then the reaction is spontaneous in nature and formation of products is less favored.
Thus, we can conclude that for the given situation positive delta G is the reason that a reaction might form products very slowly, or not at all.
