Hint :A cyclone is a low-pressure region with winds spiralling inwards in meteorology. In the Southern Hemisphere, cyclones rotate clockwise, while in the Northern Hemisphere, they rotate anti-clockwise. Hurricanes and typhoons are other names for cyclones.

Complete Step By Step Answer:
In the Northern Hemisphere, a cyclone is a system of winds revolving counter clockwise around a low pressure core. Clouds and precipitation form as the swirling air rises and cools. Tropical cyclones and middle latitude (mid-latitude) cyclones are the two forms of cyclones. Acid rain is caused by pollution. When any form of fuel is burned, a variety of chemicals are released. Smoke from a fire or emissions from a car exhaust contain more than just the visible sooty grey particles; they also contain a variety of invisible gases that can be much more detrimental to our atmosphere.
Since power plants, factories, and automobiles all burn fossil fuels, they all emit polluting gases. When certain gases (particularly nitrogen oxides and sulphur dioxide) react with the tiny droplets of water in clouds, sulphuric and nitric acids are formed. The rain that falls from these clouds is very weak acid, which is why it is called "acid rain."
Over the last one to two decades, global warming has resulted in an increase in average air temperatures near the Earth's surface. Climate scientists have been collecting systematic measurements of various weather patterns (such as temperatures, precipitation, and storms) and associated effects on climate (such as ocean currents and the chemical composition of the atmosphere) since the mid-twentieth century.
Effects of greenhouse gases: As a result of a 1°C rise in temperature,
 1. The melting of the polar ice caps raises the level of sea water. As a result, a large number of countries will be flooded.
2. The rise in the rate of evaporation of water causes unseasonal floods, cyclones, and hurricanes. Groundwater levels would drop, wreaking havoc on the agricultural sector.
So, the correct option is (a)Global warming.

Note :
Agriculture could be harmed as a result of global warming. Although the findings are not yet visible, the effects may become apparent in the coming years. Plants will struggle to survive as the global temperature rises, and will eventually die. Plants are the primary source of food for humans, so a food shortage is possible. In some countries, food shortages can lead to war and conflict.
