The correct answer to the question is option 1, Bamiyan. Bamiyan is where the world`s largest monolithic statue of Buddha has been installed. A monolithic statue refers to a statue that is carved from a single block of stone, and in this case, it is a statue of Buddha. Bamiyan is a historic region in central Afghanistan known for its Buddhist heritage. The statue, known as the Bamiyan Buddhas, was carved into the side of a cliff between the 5th and 6th centuries. It stood at a height of about 175 feet before being destroyed by the Taliban in 2001. Despite this unfortunate event, Bamiyan remains significant for its cultural and historical value.
