Explanation: The question involves evaluating the truthfulness of three statements related to the current political leadership in Delhi and historical facts about the Tughlaq Dynasty. Let's break down each statement:
1. **Chief Minister of Delhi is Arvind Kejriwal.**
- This statement is true. Arvind Kejriwal is the current Chief Minister of Delhi. He has been serving in this position since 2015, leading the Aam Aadmi Party (AAP) government. Understanding the current political leadership is crucial for anyone studying Delhi General Knowledge.
2. **Coins minted in Delhi called delhwal Muhammad-bin-Tughlaq.**
- This statement is false. There is no historical evidence to support the claim that coins minted in Delhi during the Tughlaq Dynasty were called "delhwal." The term "delhwal" is not a recognized historical term for coins from this period. Historical records and numismatic studies do not support this claim.
3. **Muhammad-bin-Tughlaq is not the founder of the Tughlaq Dynasty.**
- This statement is true. Muhammad-bin-Tughlaq was a significant ruler of the Tughlaq Dynasty, but he was not its founder. The founder of the Tughlaq Dynasty was Ghiyas-ud-din Tughlaq, who established the dynasty in 1320 AD. Muhammad-bin-Tughlaq succeeded his father, Ghiyas-ud-din Tughlaq, and ruled from 1325 to 1351 AD.
The correct answer is (D) Only 1, 3. This option correctly identifies the true statements about the current Chief Minister of Delhi and the historical fact about the founder of the Tughlaq Dynasty. It excludes the false statement about the term "delhwal" for coins.
Understanding these facts is essential for anyone studying Delhi General Knowledge, as it covers both contemporary political leadership and historical context. The Tughlaq Dynasty is a significant part of Delhi's history, and knowing the correct historical facts is crucial for accurate knowledge.
