Q. Which one of the following dynasties was ruling over North India at the time of Alexander’s invasion?

(a) Nanda

(b) Maurya

(c) Sunga

(d) Kanva

Ans: (a) Nanda  

Explanation: At the time of Alexander’s invasion of India, the dynasty ruling over North India was (a) Nanda. The Nanda Empire, also known as the Nanda dynasty, was a major power in the northern part of the Indian subcontinent during the 4th century BCE. The empire was founded by King Mahapadma Nanda and was characterized by its extensive military power and territorial expansion. However, it is important to note that Alexander’s invasion of India took place in the early 4th century BCE, and shortly after his campaign, the Maurya Empire under Chandragupta Maurya emerged as a dominant power in the region.
