Answer and explanation

Correct answer: Rancidity

In an open bottle, oil remains in contact with oxygen in air. Oxidation can produce unpleasant smell and taste in the oil; this process is called rancidity. Galvanisation is the coating of iron with zinc, so it is unrelated to keeping oil exposed to air.
