Explanation:

All are advantages of vertical farming. 

• Increased crop yield: The main advantage of utilizing vertical farming technologies is the increased crop yield that comes with a smaller unit area of land requirement. The increased ability to cultivate a larger variety of crops at once is because crops do not share the same plots of land. Vertical farming allows for, in some cases, over ten times the crop yield per acre than traditional methods. 
• Resistant to weather disruptions: Crops are resistant to weather disruptions because of their placement indoors. In other words less crops are lost to extreme or unexpected weather occurrences. The issue of adverse weather conditions is especially relevant for countries depending upon monsoon like India. 
• Prevent ecosystem disruption: Because of its limited land usage, vertical farming is less disruptive to the native plants and animals, leading to further conservation of the local flora and fauna. Traditional farming is often invasive to the native flora and fauna because it requires such a large area of arable land. 
• Environment conservation: Vertical farming can help in preventing climate change and conserve the environment. Deforestation and desertification caused by agricultural encroachment on natural biomes could be avoided. Producing food indoors reduces or eliminates conventional plowing, planting, and harvesting by farm machinery, protecting soil, and reducing emissions. 

Hence option 4th is correct.
