Concept:A settlement that develops at the point where many roads or transport routes meet is called a nodal town.
Explanation:The map of NONSO DISTRICT shows several roads approaching and meeting at NONSO.
This makes NONSO a route centre where travellers from different directions interact.
Such a junction attracts traders and encourages the exchange of goods and services.
The resulting economic activities and constant movement of people lead to the growth of the settlement.
The presence of a court, or the position at the foot of a ridge, is not shown to be the reason for growth.
Similarly, nothing in the map indicates that NONSO is a port town.
Therefore, the most probable cause of its growth is its function as a nodal town.
Answer:D. NONSO is a nodal town
