The complete worked solution.
Every step explained - no skipped algebra.
Caves in limestone regions are primarily formed through chemical weathering and solution. Rainwater, which is slightly acidic due to dissolved carbon dioxide, reacts with calcium carbonate in limestone, gradually dissolving the rock. Over time, this process enlarges joints and bedding planes in the rock, eventually creating cave systems.
Final Answer: Option B - Chemical weathering and solution
