Statement I : The cities of the second urbanization in Indian history are mainly located in the Ganga valley Statement I : Advanced iron technology, ensuring an agrarian surplus is instrumental to this process of urbanization

Statement I is true as the 'Second Urbanization' in India, beginning around the 6th century BCE, was primarily centered in the Ganga plains and its neighboring regions [2]. This phase saw the rise of major urban centers like Pataliputra, Rajgir, and Varanasi. Statement II is also true and provides the correct explanation for Statement I. The transition to a stable agrarian economy in the fertile alluvial plains of the Ganga valley was facilitated by advanced iron technology. Scholars like D.D. Kosambi and R.S. Sharma argue that iron tools, such as axes for clearing dense forests and iron ploughshares for tilling hard clayey soil, were instrumental in producing the agricultural surplus necessary to sustain non-food producing urban populations [4]. This technological shift enabled the socio-economic transformations that defined the urban character of the Mahajanapada period [4].
