Solution

The correct option is C ethanal
Aldehydes and ketones are prepared by dry distillation of calcium salts of carboxylic acids. When a mixture of calcium acetate and calcium formate is heated, we get acetaldehyde. (ethanal)

The reaction is as follows:
Ca(CH3COO)2+Ca(HCOO)2heat2CH3CHO+2CaCO3

Option C is correct.
