The correct answer is A. Formaldehyde in water.
Formaldehyde is a colorless, flammable, and toxic gas with a strong odor. It is used in a variety of products, including embalming fluid, disinfectants, and preservatives. When mixed with water, formaldehyde forms a solution called formalin. Formalin is the most common embalming fluid used today. It is effective at preventing the growth of bacteria and other microorganisms that can cause decomposition.
B. Formaldehyde in methanol is not a common embalming fluid. Methanol is a colorless, flammable, and toxic liquid that is used as a solvent and fuel. It is not as effective as formalin at preventing the growth of bacteria and other microorganisms.
C. Ethylene glycol is a colorless, flammable, and sweet-tasting liquid that is used as an antifreeze and coolant. It is not a common embalming fluid.
D. Gaseous formaldehyde is not a common embalming fluid. It is more difficult to control than formalin and can be more dangerous to use.
In conclusion, the chemical used in embalming biological materials is A. Formaldehyde in water.
