D
Both (A) and (B)
Explanation: 

Detailed explanation-1: -Given the appropriate conditions, cloud seeding can modify clouds and induce rain. This works in two ways: by producing rain when none would fall naturally; or by increasing the amount of rain that falls over a particular area.

Detailed explanation-2: -Rainmaking, also known as artificial precipitation, artificial rainfall and pluviculture, is the act of attempting to artificially induce or increase precipitation, usually to stave off drought or the wider global warming.

Detailed explanation-3: -Cloud seeding provides increased precipitation in a target area. Data suggests a slight increase in precipitation down-wind from these target areas, diminishing as distance increas-es.

Detailed explanation-4: -During winter, the clouds are mostly exacted with western disturbances. The widespread fog occurs after the passage of western disturbances. Generally, the moisture in the air is too less during winter in northern India, which limits the scope of cloud seeding.
