Which of the following is one of the common dehydrating agents?

Explanation:
Dehydration in tissue processing aims to replace water with a solvent so the tissue can be infiltrated with paraffin. Among the options, acetone acts as a dehydrating agent, effectively removing water from the tissue and often used in dehydration steps or rapid protocols. The others are used for clearing or as general solvents rather than for removing water: chloroform has historically served as a clearing solvent, xylene is a clearing agent used after dehydration to make tissue receptive to paraffin, and benzene is an old clearing solvent with toxicity concerns. Thus acetone is the appropriate dehydrating choice.
