Explanation: To understand the context of this question, we need to delve into the historical and geographical aspects of India.
**Iqtadars and Samantas:**
Iqtadars were military governors in the Islamic administrative system, particularly during the Delhi Sultanate and Mughal periods. They were granted a piece of land (iqtad) to govern and collect revenue from. On the other hand, Samantas were feudal lords in ancient and medieval India, particularly in the kingdoms of South India. They were local chieftains who held land and power under the king. Therefore, the first statement that Iqtadars were called Samantas is incorrect.
**Indian Time Zones:**
India uses a single time zone across the whole nation and its territories. This time zone is known as Indian Standard Time (IST), which is UTC+05:30. The decision to have a single time zone was made to maintain uniformity and coordination across the country, despite the vast geographical spread. This is a significant administrative decision that affects daily life, business operations, and communication across the country. Hence, the second statement is true.
**Geographical Distance:**
Imphal is the capital city of the state of Manipur in northeastern India. It is approximately 215 kilometers from Delhi, the capital of India. This distance is significant in understanding the geographical layout of the country and the connectivity between different regions. Therefore, the third statement is true.
In conclusion, the correct answer is (D) Only 2, 3, as these statements are true based on the historical and geographical facts of India. The first statement is incorrect due to the distinct roles and origins of Iqtadars and Samantas in Indian history.
