Q. Which of the following is an example of ketohexose ?

Mannose

Galactose

Maltose

Fructose

Fructose, it has ketonic group . So, it is keto hexose sugar
$Sucrose C_{12} H_{22} O_{11} + H_{2} O Hydrolysis (With aldohyde group) Glucose (aldohexose sugar) + (With ketone group) Fructose (ketohexose sugar)$
Structure of glucose and fructose is as follows
