Which of the following is a component of wine?

Explanation:
Wine is a water-based solution, with water making up by far the largest portion of its composition. This solvent holds all the dissolved substances—ethanol, acids, sugars, minerals, and aroma compounds—so water is the fundamental component. Oxygen gas can be present dissolved in the liquid, but only in small amounts and it isn’t a primary constituent. Metal ions occur in trace amounts, not as a major component. Plastic residues would indicate contamination, not a natural part of the wine. So water is the best answer because it is the major constituent that defines the liquid itself.
