Explanation: To understand the context of the question, it is essential to break down each statement and evaluate its accuracy based on historical and geographical facts about Delhi.
1. **Toronto is bigger than Delhi**: This statement is false. Delhi is the capital city of India and is one of the largest cities in the world by population. Toronto, while a significant city in Canada, is not larger than Delhi in terms of population or area. Delhi's population is significantly higher, and it covers a larger geographical area compared to Toronto.
2. **Saadat Khan was the leader of the Irani group of nobles in Delhi**: This statement is true. Saadat Khan was a prominent figure in the Mughal court and was known for his leadership of the Irani group of nobles. The Irani group consisted of nobles who were of Iranian descent and played a significant role in the Mughal administration. Saadat Khan's leadership within this group is well-documented in historical records.
3. **Delhi has a port**: This statement is false. Delhi is an inland city located in northern India. It does not have a coastline and, therefore, does not have a port. The nearest major port to Delhi is Mumbai, which is located on the western coast of India. Delhi's importance lies in its strategic location, historical significance, and role as the political and administrative center of India.
In summary, the correct answer is (A) Only 2, as it is the only statement that is true among the given options. Understanding the historical and geographical context of Delhi is crucial for correctly identifying the true statements. This question tests the ability to distinguish between factual and non-factual statements about Delhi, which is a key aspect of Delhi General Knowledge (GK).
