The correct answer is option 4: 1 and 3.

Explanation: The India monsoon is primarily influenced by the origin and mechanism related to the circulation of upper air jet stream in the troposphere (option 1) and the differential heating and cooling of the huge landmass of Asia and the Indian Ocean (option 3).

The upper air jet stream in the troposphere plays a significant role in the monsoon circulation patterns. It influences the movement of air masses and the formation of weather systems, which ultimately affects the monsoon rainfall in India.

The differential heating and cooling of the huge landmass of Asia and the Indian Ocean is another crucial factor in the origin and mechanism of the Indian monsoon. The landmass of Asia heats up faster in summer compared to the Indian Ocean, creating a low-pressure area over the land. This contrast in temperature and pressure leads to the formation of the monsoon winds, which blow from the ocean towards the land, bringing the monsoon rainfall.

Therefore, the correct answer is option 4: 1 and 3.
