The correct answer is: d) All of the above
Encroachment and urbanization are two of the biggest challenges faced by archaeological sites in Andhra Pradesh. Encroachment is the unauthorized occupation of land, and urbanization is the process of a town or city growing larger. Both of these can lead to the destruction of archaeological sites, as they can be built on or covered up.
Lack of funding and resources is another major challenge faced by archaeological sites in Andhra Pradesh. Funding is needed to carry out research and conservation work on these sites, and resources are needed to protect them from damage. Without adequate funding and resources, archaeological sites are at risk of being lost forever.
Environmental damage and erosion are also major challenges faced by archaeological sites in Andhra Pradesh. Environmental damage can be caused by natural disasters, such as floods and earthquakes, or by human activities, such as deforestation and pollution. Erosion is the process of soil being worn away by wind or water, and it can also damage archaeological sites.
All of these challenges are serious threats to the preservation of archaeological sites in Andhra Pradesh. It is important to raise awareness of these challenges and to take steps to address them.
