Which reagent turns pink in the presence of an aldehyde?

Consider all possible isomeric ketones,including stereoisomers of $MW = 100$. All these isomers are independently reacted with $NaBH_4$ ($NOTE$: stereoisomers are also reacted separately). The total number of ketones that give a racemic product$(s)$ is/are
