Which of the following is the process that occurs when an acid is mixed with a base?

Combustion refers to a chemical reaction that typically involves the rapid combination of a substance with oxygen to produce heat and light, resulting in products such as carbon dioxide and water. This process is unrelated to the interaction between acids and bases, which does not involve oxidation reactions or the release of heat in the same manner.

Condensation is the process by which a gas transforms into a liquid, often involving the release of heat as particles lose energy and come together. While it pertains to phase changes in matter, it does not involve any interaction between acids and bases, making it irrelevant to the question regarding neutralization.

Vaporization is the transition of a substance from a liquid to a gas, which can occur through boiling or evaporation. This process is entirely distinct from acid-base interactions, as it does not involve the chemical transformation or neutralization of acidic and basic properties.
