Read the source given below and answer the question.

India's contact with the World has continued through ages but her relationships through the land routes are much older than her maritime contacts. The various passes across the mountains in the north have provided passages to the ancient travellers, while the oceans restricted such interaction for a long time.

These routes have contributed to the exchange of ideas and commodities since ancient times. The ideas of the Upanishads and the Ramayana, the stories of Panchatantra, the Indian numerals and the decimal system thus could reach many parts of the world. The spices, muslin and other merchandise were taken from India to different countries. On the other hand, the influence of Greek sculpture and the architectural styles of domes and minarets from West Asia can be seen in different parts of our country.

Answer the MCQ by choosing the most appropriate option.

Which geographical feature has provided passage to the ancient travellers in India?
