Which of the following geographical features predominantly influences the spatial distribution of economic infrastructure and transport costs in Arunachal Pradesh?

💡 Solution & Explanation

The rugged mountainous terrain of the Eastern Himalayas heavily shapes the economic landscape of Arunachal Pradesh, leading to high infrastructure development costs and isolated market settlements. Flat alluvial plains are restricted to narrow river valleys in foothills adjoining Assam. The challenging topography restricts railway connectivity to specific border-fringe locations and makes road construction both capital-intensive and vulnerable to monsoon landslides. Road density remains a critical metric for regional economic integration in hilly states.
