Bmay cause frothing
Chas a higher chloride content
Dpromotes scale buildup
AI Explanation
The correct answer is B) may cause frothing. Antifreeze solutions containing ethylene glycol should not be mixed with corrosion protection oils because the resultant mixture can cause frothing. Frothing occurs when the two liquids emulsify, creating an undesirable foam-like substance. This frothing can lead to issues with the engine's cooling system and potentially damage components. The other answer choices are incorrect, as mixing antifreeze and corrosion protection oils does not make the mixture dangerously flammable, increase the chloride content, or promote scale buildup.
