Solution

The correct option is C Concentrated sulphuric acid
A dehydrating agent is a substance that dries or removes water from a material. In the reaction,

$C_{6} H_{12} O_{6} H_{2} S O_{4} - --- \to c o n c . 6 C + 6 H_{2} O$

The Concentrated sulphuric acid extracting the water molecule from glucose molecule thus $H_{2} S O_{4}$ is the dehydrating agent.
