Which term refers to a sharp, paint-like odor due to the deterioration of fats?

Explanation:
Rancid describes fats that have deteriorated, producing a sharp, paint-like odor. This odor comes from the oxidation and breakdown of fats into volatile compounds like aldehydes and ketones, which give that characteristic off-smell. The other terms don’t capture fat spoilage: slime formation is a texture change from microbial growth, sourness arises from acids produced by fermentation or spoilage, and putrefaction refers to protein breakdown with foul odors. So the term that best matches a sharp paint-like odor due to fat deterioration is rancid.
