The correct answer is option 2: aqueous formaldehyde. Formalin is a solution composed of formaldehyde gas dissolved in water.

Option 1, aqueous ferrous sulphate, is a different compound and not used for storing dead organs.

Option 3, aqueous formic acid, is also a different compound and not used for storing dead organs. Formic acid is commonly used as a preservative for biological specimens in laboratories, but it is not the main component of formalin.

Option 4, aqueous ferric alum, is yet another compound and not used for storing dead organs. Ferric alum is a type of aluminium salt and is primarily used in certain industrial applications and as a mordant in dyeing fabrics.

It is important to note that formalin is a toxic substance and should be handled with care. The use of formalin in preserving dead organs helps to prevent decay, maintain the structure of the tissues, and inhibit microbial growth.
