The process most likely responsible for the formation of limestone caves is carbonation.

To determine the process most likely responsible for the formation of limestone caves, we can analyze the options given and understand each process.

1. Oxidation: Oxidation is a process where a substance combines with oxygen. It typically results in the formation of rust or other similar compounds. While oxidation can occur in certain environments, it is not the primary process responsible for the formation of limestone caves.

2. Abrasion: Abrasion refers to the mechanical wearing away or erosion of a material by friction. While abrasion can contribute to the shaping of limestone caves over a long period, it is not the primary process responsible for their formation.

3. Carbonation: Carbonation, also known as carbonic acid reaction, is a chemical reaction between carbon dioxide gas dissolved in water and minerals containing calcium, such as limestone. This process is the primary mechanism responsible for the formation of limestone caves. Over time, carbonation dissolves the limestone, creating openings and chambers in the rock, leading to the formation of caves.

4. Hydrolysis: Hydrolysis is a chemical reaction that involves breaking down compound molecules with water. While hydrolysis can play a minor role in the weathering of limestone, it is not the primary process responsible for the formation of limestone caves.

Based on the explanations above, the process most likely responsible for the formation of limestone caves is carbonation. Therefore, the correct answer to the question is "carbonation."
