Concept:Al-Biruni, a scholar from Uzbekistan, visited India over a thousand years ago and wrote detailed observations about Indian customs and architecture, especially water storage structures.
Explanation:Al-Biruni was born in 973 CE in Khwarizm, now part of Uzbekistan.
He traveled to India and carefully noted everything he saw.
He focused on aspects that were very different from his own homeland, such as building styles and daily life.
He wrote in detail about Indian ponds, describing how huge rocks were piled up and joined with iron rods to create raised platforms around lakes.
His writings preserved valuable information about that period.
In 1973, on the millennium of his birth, the Indian government issued a stamp in his honor.
Therefore, statement (A) is true because he came more than a thousand years ago.
Statement (B) is true because he especially wrote about ponds that were different from those in his country.
Statement (C) is true because his observations help us understand India's history.
Answer:All three statements are correct. The correct option is C. A, B and C.
