The correct answer is b. Collision of Indian tectonic plate with Eurasian plate; uplift of the Tibetan Plateau; formation of the Gobbi desert; yearly monsoon wind cycle.
The collision between the two tectonic plates took/is taking tens of millions of years. It is what caused the Tibetan Plateau to form and it's uplift is due to the ongoing collision of the two plates, the Gobbi desert is formed because of the uplift of the land that is caused by the collision of the two plates, and the yearly monsoon cycle is affected by the geography of the Asian land.
