The correct answer is - B. rainfall and chemical reaction.
The Great Buddha statue is under constant change and it is slowly but surely weathering bit by bit. The two biggest reasons for this are:
- The rainfall; the water from the rainfall is one of the biggest causes of weathering of the rocks, the water is known to decompose the rocks over time and the Great Buddha statue which is on an open space is not an exception of its influence.
- The chemical reactions; China has a huge problem with pollution. There's lots of pollutants in the air that are causing serious damage to most things, including the Great Buddha statue, and they contribute to quicker decomposing with their corrosive power and change in colour than anything else.
