The by-products of oxidation, as a result of water contamination of hydraulic oil, are generally _______________.

Aharmless and have no effect on system components
Balways neutralized by oil additives
Cgums, varnishes, and acids
Dremoved by cellulose type filters
AI Explanation

The correct answer is C) gums, varnishes, and acids. The by-products of oxidation due to water contamination of hydraulic oil are generally gums, varnishes, and acids. These corrosive compounds can damage system components and impair the performance of the hydraulic system. They are not harmless (option A) and are not always neutralized by oil additives (option B). While cellulose type filters may help remove some of these contaminants (option D), they do not prevent the formation of the oxidation by-products in the first place.
