Concept:A simple ketone, also called a symmetrical ketone, has the same groups attached to both sides of the carbonyl group $>\mathrm{C=O}$.Explanation:In a simple ketone, the two substituents on the carbonyl carbon must be identical.Acetophenone is $\mathrm{C_6H_5COCH_3}$, so the groups are different.Butanone is $\mathrm{CH_3COCH_2CH_3}$, so the groups are different.Benzophenone is $\mathrm{C_6H_5COC_6H_5}$, so both groups are identical phenyl groups.Pentan-2-one is $\mathrm{CH_3COCH_2CH_2CH_3}$, so the groups are different.Therefore, benzophenone is the simple ketone.Answer:C. Benzophenone
