Concept:The Vindhya Range is a natural mountain barrier in central India that traditionally separates the northern and southern parts of the country.
Explanation:The Vindhya Range runs through Madhya Pradesh, Uttar Pradesh, Gujarat, and Rajasthan.
It has an average elevation of 450–600 metres, but its geographical position makes it a clear boundary.
It divides the Indo-Gangetic plains in the north from the Deccan Plateau in the south.
Historically, the range has been considered the traditional divide between North and South India in terms of culture and language.
It also influences distinct climatic conditions on either side.
Now examine other options: Option B (East and West India) has no single mountain range separating them; the Aravalli Range lies in the west but does not divide east from west.
Option C (Western Ghats and Eastern Ghats) are both located in South India, not separating north and south.
Option D (Himalayas and Deccan Plateau) are far apart and do not form a dividing line between north and south.
Therefore, the Vindhya Range correctly separates North and South India.
Answer:Option A: North and South India
