Which of the following has the largest percentage of carbon in the compound?

Question

BlackTom AI · Accepted Answer

The prompt asks which compound has the largest percentage of carbon. 
First, I note that the only provided option is a. C6H6, and there are no other choices to compare against. 
To evaluate carbon percentage in general, one would calculate the mass fraction of carbon in each compound (mass of carbon / molar mass of compound × 100%). For benzene, C6H6, the molar mass is about 78.11 g/mol, with carbon contributing 6 × 12.01 ≈ 72.06 g of that mass, giving a carbon mass percentage of roughly 72.06 / 78.11 ≈ 92.3%. 
If other candidates were present, we would similarly compute their carbon percentages and compare. For example, hydrocarbon formulas with a high carbon-to-hydrogen ratio tend to have high carbon percentages, but compounds with many hydrogens can reduce the overall carbon percentage even if they have many carbons, depending on the exact composition. 
With only C6H6 available, there is no competing option provided to establish a relative comparison, so determining the largest percentage among multiple choices cannot be completed here. 
In a typical scenario, you would compare the carbon mass fraction across all given options and select the one with the highest value. If another option had, say, a higher carbon-to-hydrogen ratio or a larger relative amount of carbon, that would win. If all else were equal, the molecule with more carbon atoms relative to total mass would have the larger percentage. 
Given the absence of other options in this question, the analysis stops at recognizing that C6H6 is strongly carbon-rich, but a definitive 'largest' designation cannot be confirmed without additional alternatives to compare.
