Solution:Concept- On the basis of temperature, the atmosphere is divided into strata. Troposphere, stratosphere, mesosphere, and thermosphere are these strata. The exosphere is a second zone that is located 500 kilometres above the surface of the Earth. In addition, the weather takes place in the lowest part of the atmosphere.
The layer in which the weather takes place is the troposphere. The lowest layer of the atmosphere, known as the troposphere, is where the majority of the water vapour that contributes to the formation of many weather systems is found. As a result, the troposphere is the location of all meteorological events.
Additionally, this layer begins at the Earth's surface and rises to a height of 7–20 km.
Water vapours and mature particles make up this stratum. The temperature drops by 1C for every 165 metres of height.
Furthermore, 99% of the water vapour in the atmosphere is located in this layer, which also contains 75% of the air in the atmosphere and most clouds.
The weather is basically made because of the water vapours and it is present in the lowest layer which is the troposphere.
Hence, the correct answer is option 2.
